Answer:
[tex]y\leq -3[/tex]
Step-by-step explanation:
[tex]3y+2 \geq 5y+8 \\\\3y\geq 5y+6\\\\-2y\geq 6\\\\y\leq -3[/tex]
Hope this helps!
Answer:
-3 ≥y
Step-by-step explanation:
3y + 2 ≥ 5y +8
Subtract 3y from each side
3y-3y + 2 ≥ 5y-3y +8
2 ≥ 2y +8
Subtract 8 from each side
2-8 ≥ 2y +8-8
-6 ≥ 2y
Divide by 2 on each side
-6/2 ≥ 2y/2
-3 ≥y

Answer:
7 7/24
Step-by-step explanation:
first put the wholes inside the fraction:
[tex]1 \frac34 = \frac44 + \frac34 = \frac74[/tex]
[tex]4 \frac16 = \frac{24}{6} + \frac16 = \frac{25}{6}[/tex]
Then multiply numerator times numerator, denominator times denominator and take out wholes again:
[tex]\frac74 \times \frac{25}{6} = \frac{7 \times 25}{4 \times 6} = \frac{175}{24} = 7 \frac{7}{24}[/tex]
The price of a stock decreased by 60 cents one week, decreased 10 cents the next week, and decreased another 20 cents the following week. What is the average change in the price of the stock over the three weeks? A. –270 cents per week B. –90 cents per week C. –87 cents per week D. –30 cents per week
Answer:
D
Step-by-step explanation:
In 3 weeks the stock decreased 60 + 10 + 20 = 90 cents so it decreased about 90 / 3 = 30 cents per week so it is D.
Answer:
The answer is D

The student council at Clarksville High School is making T-shirts to sell for a fundraiser, at a price of $10 apiece. The costs, meanwhile, are $8 per shirt, plus a setup fee of $98. Selling a certain number of shirts will allow the student council to cover their costs. What will the costs be? How many shirts must be sold?
Answer:
Costs are $490
49 shirts are sold
Step-by-step explanation:
98 + 8x = 10x
98 = 2x
49 = x
98 + 8(49) = $490 in costs
49 shirts sold

amanda has a board that is 7 feet long. how many 1/4 foot sections can she cut from this board
Answer:
28
Step-by-step explanation: You need to divide 7 by 1/4. Whenever you divide fractions you keep the first number as it is, change the sign to multiplication and write the reciprocal of the second fraction which is you have to flip the fraction. It is going to be 7 times 4/1. Which is 28/1 which is 28.
Consider the equation y=-x^2-7x+12
Answer:
y = (x + 4)(x + 3)
Step-by-step explanation:
y = x ^2 + 7x + 12
The two numbers must add up to 7 and has a product of 12, and since the equation is all positive, then the two numbers are positive too.
So y = (x + 4)(x + 3) is the answer.
Check:
y = (x + 4)(x + 3)
y = x(x + 3) + 4(x + 3) distributive property
y = x^2 + 3x + 4x + 12
y = x^2 + 7x + 12

Fred is planning a fundraiser where he will collect $4.50 for every mile he runs. He will be running on a typical track, that has two straight lengths of 300 feet each, and two curved parts that are in the shape of semicircles with 200 foot diameters
He runs around the track exactly 15 times. To the nearest cent, how much money did he collect?
Answer:
Step-by-step explanation:
The diameter of each curved path is 200 feet. Since the two curved semi circular paths are equal, they would form a circle. It means that the distance around the two semi circular paths would be the circumference of the circle. Formula for determining the circumference of the circle is π × diameter. It becomes
200 × 3.14 = 628 feet
Total distance around the track would be
300 + 300 + 628 = 1228 feet
5280 feet = 1 mile
1228 feet = 1228/5280 = 0.23 mile
If he runs around the track exactly 15 times, it means that the number of miles covered is
0.23 × 15 = 3.45 miles
Since he will collect $4.50 for every mile he runs, the amount of money that he collected is
4.5 × 3.45 = $15.5
sheena is shocking a shelf with bags of flour that weigh 5 1/4 pounds each if sheena stocks the shelf with 13 bags of flour find the combined weight of 13 bags
Answer:
[tex]68\frac{1}{4}[/tex] pounds
Step-by-step explanation:
The combined weight of 13 bags is 13 multiplied by the weight of each bag.
The weight of each bag is [tex]5\frac{1}{4}[/tex] pounds. Therefore, the weight of 13 bags is:
[tex]5\frac{1}{4} * 13\\ \\= \frac{21}{4} * 13\\[/tex]
[tex]= 68\frac{1}{4}[/tex] pounds
If f(x)= 3x^2-2x+4.and g(x)= 5x^2 +6x -8find(f-g)(x)
Answer:
-2x^2-8x+12
Step-by-step explanation:
f(x)= 3x^2-2x+4
g(x)= 5x^2 +6x -8
(f-g)(x) = 3x^2-2x+4-(5x^2 +6x -8)
Distribute the minus sign
(f-g)(x) = 3x^2-2x+4-5x^2 -6x +8
Combine like terms
-2x^2-8x+12

Step-by-step explanation:
You are driving to visit a friend in another state who lives 440 miles away. You are driving 55 miles per hour and have already driven 275 miles. Write and solve an equation to find how much longer in hours you must drive to reach your destination. A. 55h + 275 = 440 ; h=3 B.55h - 275 = 440 ; h= 13 C.440h -275 = 55 ; h =0.75 D. 55h +275h = 440 ; h=1.3
Answer:
A. 55h + 275 = 440; h=3
Step-by-step explanation:
Since all answer choices have a different H= , finding how many hours you have left to drive will give you the right answer.
You've already driven 275 miles in your 440 mile trio so you can subtract the 275 to find out how much you will still need to drive.
440 - 275 = 165
You already know that you are driving at 55 mph so divide 165 by 55 and the answer is three.
Option A was the only answer choice which listed h=3 so that is the correct answer.
Ok so I’m in high school and I forgot everything I learned in 6-7th grade so what is 14/2 + 12/6 I got 54/6 but I don’t know what to do to get it into simplest form btw I’m very dumb so please explain it like you would to a 4yr old
Answer:9
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator. Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1. (14/2 x 3/3)+(12/6 x 1/1). Complete the multiplication and the equation becomes 42/6+12/6. The two fractions now have like denominators so you can add the numerators. 42+12/6=54/6. Divide 54 by 6 and get 9. hope this helps :)
7x + 2 = -19 (b) 3x - 1/3 = 5 (c) 5x - 4 = 21 (d) -7x = 21 (e) 18 - 7x = -3 (f) 3(x + 4) = 21 (g) 3x - 9 = 5x - 3 (h) 4x + 6 - 7x + 9 = 18 (i) - 4/9 x = - 36 (j) -7/8x - 6 = 8 can any please elp me find the variables in the question
Answer:
Step-by-step explanation:
a)7x + 2 = -19 {subtract 2 from both sides}
7x + 2 - 2 = -19 - 2
7x = -21 {Divide both sides by 7}
7x/7 = -21/7
x = -3
b) 3x - 1/3 = 5
3x - 1/3 +1/3 = 5 + 1/3 {Add 1/3 to both sides}
3x =15/3 + 1/3
3x =16/3
3x/3 = 16/3*3 {Divide both sides by 3}
x =16/9
x =1 7/9
c) 5x - 4 = 21
5x -4 + 4 = 21 +4 {Add 4 to both sides}
5x = 25
5x/5 = 25/5 {Divide both sides by 5}
x = 5
d) -7x = 21 {Divide both sides by -7}
-7x/-7 = 21/-7
x = -3
e) 18 - 7x = -3
18 - 7x - 18 = -3 - 18 {Subtract 18 from both sides}
-7x = -21 {Divide both sides by -7}
-7x/-7 = -21/-7
x = 3
f) 3(x+4) = 21 {use distributive property}
3x + 3*4 = 21
3x + 12 = 21
3x + 12 - 12 = 21 - 12 {Subtract 12 from both sides}
3x = 9 {Divide both sides by 3}
3x/3 = 9/3
x = 3
g) 3x - 9 = 5x - 3 {add 9 to both sides}
3x - 9 + 9 = 5x - 3 + 9
3x = 5x + 6
3x - 5x = 5x + 6 - 5x { subtract 5x form both sides}
-2x = 6 {Divide both sides by -2}
-2x/-2 = 6/-2
x = -3
h) 4x + 6 - 7x + 9 = 18 {Add the like terms}
-3x + 15 = 18 {Subtract 15 from both sides}
-3x + 15 -15 = 18 - 15
-3x = 3 {Divide both sides by -3}
-3x/-3 = 3/-3
x = -1
[tex]i) \frac{-4}{9}x = -36[/tex]
Multiply both sides by 9
[tex]9*\frac{-4}{9}x =9*-36[/tex]
-4x = -324 {Divide both sides by -4}
-4x/-4 = -324/-4
x = -81
[tex]j)\frac{-7}{8}x - 6 = 8[/tex] {Add 6 to both sides}
[tex]\frac{-7}{8}x-6+6=8+6\\\\\frac{-7}{8}x=14\\[/tex] {Multiply both sides by 8}
[tex]\frac{-7}{8}x*8=14*8\\\\-7x=14*8\\[/tex] {Divide both sides by -7}
[tex]\frac{-7}{-7}x=\frac{14*8}{-7}[/tex]
x =-2*8
x = -16

Then add the tip to the original number.
Even the measure ofAngle six is 62 what is the measure of angle five
∠5 = 118
Step-by-step explanation:
If you look closely at this image, you can see that ∠6 and ∠5 together will be equal to line c.
A straight line is equal to 180 so if we do...
[tex]180-62[/tex]
= 118.
∠5 will be equal to 118.
If we go even further, because vertical angles are congruent...
∠7 = 62
∠8 = 118
Answer:
[tex] m \angle \: 6 = 118 \degree[/tex]
Step-by-step explanation:
[tex]m \angle \: 5 + m \angle \: 6 = 180 \degree.. (straight \: line \: \angle s) \\ \because \: m \angle \: 5 = 62 \degree \\ \therefore \: 62 \degree+ m \angle \: 6 = 180 \degree \\ \therefore \: m \angle \: 6 = 180 \degree - 62 \degree \\ \huge \red{ \boxed{\therefore \: m \angle \: 6 = 118 \degree}}[/tex]
