The lions and the tigers played a football game the lions scored three more than three times the number of points the tigers scored
This question is incomplete
Complete Question
The lions and the tigers played a football game. The Lions scored three more than three times the number of points the Tigers scored. The total number of points scored by both teams is 31. How many points were scored by each team?
Answer:
The number of points scored by the Lions = 24
The number of points scored by the Tigers = 7
Step-by-step explanation:
Let the number of points scored by the lion = l
The number of points scored by the tiger = t
The Lions scored three more than three times the number of points the Tigers scored.
l = 3 + 3(t)
The total number of points scored by both teams is 31.
= l + t = 31
3 + 3t + t = 31
4t = 31 - 3
4t = 28
t = 28/4
t = 7 points
Note:
l + t = 31
I = 31 - t
l = 31 - 7
l = 24 points
The number of points scored by the Lions = 24
The number of points scored by the Tigers = 7

If n is an odd number, then its remainder is 1 when I divide it by 2.
17 is an odd number. What conclusion can be made?
Answer: Its remainder is 1 when you divide 17 by 2.
In other words, 17/2 = 8 remainder 1.
The 8 is the quotient.
The reason why we know we get a remainder 1 is because the condition of "if n is an odd number" and here n = 17 is odd. So the first condition is met allowing us to use the full "if, then" statement given to us.
Point P partitions directed segment AB in the ratio of 3:4.
What is the total number of congruent sections/parts? (what
is the k value?)
how many congruent sections are there
Answer:
Total number of congruent sections/parts = 7
[tex] k = \frac{3}{7} [/tex]
Step-by-step explanation:
Given that partitions directed segment AB such that AP : PB = 3 : 4, this implies that:
There are 7 parts/congruent sections that AB has been divided into.
Also, point P, partitions AB in the ratio 3:4.
Therefore, there are a total of 7 congruent sections/parts.
Value of k:
Value of k = numerator of the original ratio ÷ sum of numerator and denominator of the original ratio
[tex] k = \frac{3}{3 + 4} [/tex]
[tex] k = \frac{3}{7} [/tex]
Sarah graphed the line that represents the equation y=−5x.
Which ordered pairs represent points on the line?
Select all that apply.
(6,−30)
(−2,−10)
(5,25)
(−3,15)
(1,−5)
Answer:
the ordered pairs which represent points on the line are
(6, -30) ⇒ A
(-3, 15) ⇒ D
(1, -5) ⇒ E
Step-by-step explanation:
To find the ordered pairs represents points on the line y = -5x, substitute x in the equation by the x-coordinate of each point if the value of y equals the y-coordinate of the point, then the point lies on the line
∵ y = -5x
∵ The ordered pair is (6, -30)
∴ x = 6 and y = -30
→ Substitute x in the equation by 6 to find y
∵ y = -5(6)
∴ y = -30
→ y has the same value of the y-coordinate of the point
∴ (6, -30) represents point on the line
∵ The ordered pair is (-2, -10)
∴ x = -2 and y = -10
→ Substitute x in the equation by -2 to find y
∵ y = -5(-2)
∴ y = 10
→ y does not have the same value of the y-coordinate of the point
∴ (-2, -10) does not represent a point on the line
∵ The ordered pair is (5, 25)
∴ x = 5 and y = 25
→ Substitute x in the equation by 5 to find y
∵ y = -5(5)
∴ y = -25
→ y does not have the same value of the y-coordinate of the point
∴ (5, 25) does not represent a point on the line
∵ The ordered pair is (-3, 15)
∴ x = -3 and y = 15
→ Substitute x in the equation by -3 to find y
∵ y = -5(-3)
∴ y = 15
→ y has the same value of the y-coordinate of the point
∴ (-3, 15) represents a point on the line
∵ The ordered pair is (1, -5)
∴ x = 1 and y = -5
→ Substitute x in the equation by 1 to find y
∵ y = -5(1)
∴ y = -5
→ y has the same value of the y-coordinate of the point
∴ (1, -5) represents a point on the line
You will use the GeoGebra geometry tool to divide a line segment in a given ratio. Go to line segment ratios, and complete each step below. If you need help, follow these instructions for using GeoGebra.
Question 1
Any line segment that is not horizontal or vertical can be represented as the hypotenuse of a right triangle whose legs are aligned with the x- and y-axes. In GeoGebra, is shown as the hypotenuse of such a triangle. You will divide in the ratio 2 : 3 using the ideas you’ve seen so far in the lesson:
Find and record the lengths of the horizontal and vertical sides of the right triangle.
Find and record the x-coordinate of a point that divides the horizontal side in the ratio 2 : 3. Use the formula from the lesson to guide you:
.
Find and record the y-coordinate of a point that divides the vertical side in the ratio 2 : 3. Use the formula from the lesson to guide you:
Consider a point C that has the x-coordinate of the point that divides the horizontal side in the ratio 2 : 3 and the y-coordinate of the point that divides the vertical side in the ratio 2 : 3. Write down the coordinates of point C. This is the point that divides in the ratio of 2 : 3.
Answer:
(2.6,1.8)
Step-by-step explanation:
length of horizontal side = (xB − xA) = 4 units
length of vertical side = (yB − yA) = 2 units
To find the x-coordinate of the point that divides the horizontal side in the ratio 2 : 3, first convert the ratio between the parts into the fraction of the sum that the first part is equal to: a/a+b= 2/2+3= 2/5
Multiply the length of the horizontal side by the fraction, and then add the result to the x-coordinate of point A: Xc= Xa + (a/a+b) (Xb - Xa) = 1+ (2/5 x 4) = 2.6
Multiply the length of the vertical side by the fraction, and then add the result to the y-coordinate of point A: Yc= Ya + (a/a+b) (Yb - Ya) = 1+ (2/5 x 2) = 1.8
It follows that point C is located at (2.6, 1.8).
Answer:
The coordinates of point C is (2.6,1.8)

You have a coupon for 30% off your dinner. Your total bill was $50. You also need to pay a 7% sales tax and leave a 22% tip. With the discount, tip + tax included, how much was your dinner?
Answer:
$49.50
Step-by-step explanation:
30% of $50 = $15.00
7% of $50 = $3.50
22% of $50 = $11.00
$50.00 - $15.00 = $35.00
$35.00 + $3.50 = $38.50
$38.50 + $11.00 = $49.50
How much was your dinner?
The total amount is $49.50, so only a total of 50 cents is being taken off from the whole payment of the dinner. (≧◡≦) (o´∀`o) (´• ω •`) (＾▽＾) (⌒ω⌒)

Step-by-step explanation:
7) ∠1 + 30 = 180 {linear pair}
∠1 = 180 - 30
∠1 = 150
8) ∠2 = 30 {Vertically opposite angles are congruent}
9) In ΔLMN,
∠L + ∠N + ∠M = 180 {angle sum property of triangle}
50 + 30 + ∠M = 180
80 + ∠M = 180
∠M = 180 - 80
∠M = 100°
10) Sum of exterior angle of a triangle equals to sum of opposite interior angles.
∠B + ∠A = ∠BCD
30 + ∠A = 80
∠A = 80 - 30
∠A = 50

Toni is shopping for clothes at the store she buys 8 shirts for $8.00 what is the unit rate for the shirts?
Answer:
$1.00
Step-by-step explanation:
The unit rate in this scenario would be $1.00 , meaning that Toni is paying $1.00 for every shirt. This can be calculated by dividing the total price that she is paying for the shirts by the total number of shirts that Toni is purchasing like so...
$8.00 / 8 = $1.00 per shirt
The unit rate is basically the value over the denominator of 1 which would be the case as seen above since $1 buys 1 shirt ([tex]\frac{1 dollar}{1 shirt}[/tex]) as opposed to $8 dollars 8 shirts ([tex]\frac{8 dollars}{8 shirts}[/tex]) as mentioned in the question.

Miss Croft made snack bags for the picnic that contain three types of snacks: packages of crackers, packages of cookies, and candy bars. A snack bag containing 6 of each type of snack costs $21.00. A snack bag containing 8 packages of crackers, 5 packages of cookies, and 10 candy bars costs $26.00. A snack bag containing 5 packages of crackers, 4 packages of cookies, and 7 candy bars costs $18.50. Solve a system of three linear equations in three variables to determine the cost of one candy bar.
Answer: $1.25
Step-by-step explanation:
Let the cost of cracker be a.
Let the cost of cookies be b.
Let the cost of candy bars be c.
From the question,
6a + 6b + 6c = $21
8a + 5b + 10c = $26
5a + 4b + 7c = $18.50
To solve this, we first pick any two pairs of equation. This will be:
6a + 6b + 6c = $21 ....... i
8a + 5b + 10c = $26 ....... ii
Multiply equation i by 8
Multiply equation ii by 6
48a + 48b + 48c = $168 ....... iii
48a + 30b + 60c = $156 ....... iv
Subtract equation iv from iii
18b - 12c = 12
We then pick another two pairs
8a + 5b + 10c = $26
5a + 4b + 7c = $18.50
Multiply equation i by 5
Multiply equation ii by 8
40a + 25b + 50c = $130
40a + 32b + 56c = $148
Subtract the equations
-7b - 6c = -18
Then, solve the new equations formed
18b - 12c = 12 ....... v
-7b - 6c = -18 ....... vi
Multiply equation i by -7
Multiply equation ii by 18
-126b + 84c = -84
-126b - 108c = -324
Subtract the equations
192c = 240
c = 240/129
c = $1.25
From equation v, put the value of c
18b - 12c = 12
18b - 12($1.25) = 12
18b - $15 = $12
18b = $27
b = $27/18
b = $1.5
Since,
6a + 6b + 6c = $21
6a + 6($1.5) + 6($1.25) = $21
6a + $9 + $7.5 = $21
6a + $16.5 = $21
6a = $21 - $16.5
6a = $4.5
a = $4.5/6
a = $0.75
One candy bar cost $1.25
The cost of one candy bar is $1.5 and this can be determined by forming the linear equation with the help of given data.
Given :
Miss Croft made snack bags for the picnic that contain three types of snacks: packages of crackers, packages of cookies, and candy bars.A snack bag containing 6 of each type of snack costs $21.00. A snack bag containing 8 packages of crackers, 5 packages of cookies, and 10 candy bars costs $26.00. A snack bag containing 5 packages of crackers, 4 packages of cookies, and 7 candy bars costs $18.50.Form the linear equation in order to determine the cost of one candy bar. Let 'x' be the cost of crackers, 'y' be the cost of cookies, and 'z' be the cost of candy bars.
So, the linear equation that represents the situation "A snack bag containing 6 of each type of snack costs $21.00" is:
6x + 6y + 6z = 21 --- (1)
The linear equation that represents the situation "A snack bag containing 8 packages of crackers, 5 packages of cookies, and 10 candy bars costs $26.00" is:
8x + 5y + 10z = 26 --- (2)
The linear equation that represents the situation "A snack bag containing 5 packages of crackers, 4 packages of cookies, and 7 candy bars costs $18.50" is:
5x + 4y + 7z = 18.50 --- (3)
Simplify all three equations in order to determine the value of 'x', 'y', and 'z'.
z = $1.25
y = $1.5
x = $0.75

How many grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% w/w of salicylic acid?
Answer:
4.79 g
Step-by-step explanation:
mass of salicylic acid = ??
Mass of polyethylene = 75 g
% w/w concentration = 6% w/w
Let the mass of salicylic acid be x
Let the mass of solution = 75 + x
from
% w/w = mass of solute/ mass of solution * 100
Hence concentration of salicylic is;
6 = (x/75 + x) * 100
6/100 = x/75 + x
0.06 (75 + x) = x
4.5 + 0.06x =x
4.5 = x-0.06x
x = 4.5/0.94
x= 4.79 g
4.79 grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% of salicylic acid.
To determine how many grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% of salicylic acid, the following calculation must be performed:
100 - 6 = 94 94 = 75 6 = X 6 x 75/94 = X 450/94 = X 4.7872 = X
Therefore, 4.79 grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% of salicylic acid.
