Solve for m.
m − 10 + 6m = 10 + 2m
m =
Answer:
m = 4
Step-by-step explanation:
m−10+6m=10+2m
7m-10=10+2m
Subtract 2m from both sides
5m-10=10
Add 10 to both sides
5m=20
Divide both sides by 5
m=4
Answer:
m=4
Step-by-step explanation:
m − 10 + 6m = 10 + 2m
7m - 10 = 10 + 2m (subtract 2m from both sides)
7m - 10 - 2m = 10
5m - 10 = 10 (add 10 to both sides)
5m = 10 + 10
5m = 20 (divide both sides by 5)
m = 20/5
m = 4

If the length of AC equals 50, what is the length of the midsegment DE?
Answer:
Length of DE is 25.
Step-by-step explanation:
Right, so this is something called midsegment theorem. ΔDBE is similar (but not congruent) to ΔABC because of the angles they share. Since DE is described as a midsegment, this means BE=EC and BD=DA; so ΔDBE is half the size of ΔABC, meaning its side lengths are also half that of the larger triangle.

to find the slope 'm', follow these steps:
STEP 1
Mean (X) = \frac{4+6+8+13+11}{5}=8.4
Mean(Y)= \frac{17+12+9+4+3}{5}=9
STEP 2
Refer to Picture 2 and Picture 3 for the working out of ( x_{i} -mean(X)) and ( y_{i} -mean(Y))
( x_{i}-X)( y_{i}-Y) =(-4.4)(8)+(-2.4)(3)+(-0.4)(0)+(2.6)(-5)+(4.6)(-6)
( x_{i}-X)( y_{i}-Y) =(-35.2)+(-7.2)+0+(-13)+(-27.6)=-83
STEP 3:
( x_{i}-X) ^{2} = (-4.4)^{2}+ (-2.4)^{2}+ (-0.4)^{2}+ (2.6)^{2}+ (4.6)^{2}=53.2
STEP 4:
To find slope, divide answer in STEP 2 by the answer in STEP 3
m= \frac{-83}{53.2} =-1.56
STEP 5:
b=Mean(Y)-[slope*mean(X)]
b=9-(-1.56*8.4)=22.105
We have the slope, m=-1.56 and y-intercept of 22.105
The equation of line is
y=22.105-1.560x

Step-by-step explanation:
Write a phrase for the algebraic expression:
s +7
There are many possible answers for this.
One example is below.
S = the number of stations included when a person orders basic cable, write an expression for the number of stations a person has if he ordered basic cable and 7 premium channels.
We can represent this as s + 7.
The value that we don't know is the number of
stations included when a person orders basic cable.
So we can represent that as s.
Then, since the person ordered 7 premium channels, that means he
is adding an additional 7 channels to his basic cable plan.
So we can represent this as s + 7.
Answer:
a number plus 7
Step-by-step explanation:
s+7
Let s represent an unknown number

If f(x) = 1-x2 and g(x) = 1 - x which is the rule of function (f – g)(x)?
Answer:
-x^2 +x
Step-by-step explanation:
f(x) = 1-x^2
g(x) = 1 - x
f(x) - g(x) = 1-x^2 - (1 - x )
Distribute the minus sign
= 1-x^2 -1 +x
Combine like terms
= -x^2 +x
Jack picked 60Apples from an apple tree he uses 12 of them to make applesauce replaces the remaining apples equally into six gift basket which equation can be used to determine the number of Apples place is in to each gift basket?
Answer
60 apples minus how many she picked (12) or 60-12 divided by 6 baskets. The answer will be 60-12=48. 48 divided by 6 equals 8. The ANSWER IS 8
Step-by-step explanation:
The formula used to calculate how many apples should be included in each gift basket is as follows:
6x = 48
What are permutation and combination?A permutation is an orderly arrangement of things or numbers. Combinations are a means to choose items or numbers from a collection or set of items without worrying about the items' chronological order.
Jack has 48 apples left after using 12 of the 60 apples he took from the tree to make applesauce.
The leftover apples will be distributed equally among six gift baskets, he said. He puts x apples in each present basket, where x is the number of apples. Then he adds six times as many apples to each of the six gift baskets.
He has to fill the gift baskets with 48 apples, thus we can create an equation:
6x = 48
We may divide both sides of the equation by 6 after finding the value of x:
x = 8
Hence, Jack needs to fill each of the six gift baskets with 8 apples.

the average newborn baby weighs 7.9 lbs with standard deviation of approximately 0.5lbs. if this is normal distribution then what percentage of babies would be at least 9.4 lbs.
Answer:
99.87%
Step-by-step explanation:
We would be using the Z score formula to solve this question. The formula is given as:
z = (x-μ)/σ,
Where :
x = observed value = 9.4lbs
μ = mean or average value = 7.9lbs
σ = Standard deviation = 0.5lbs
z = (9.4- 7.9)/0.5
z = 3
The z score = 3
Using the normal distribution table to find which percentage of babies would be at least 9.4lbs
P(x<Z) = 0.99865
Converting this to percentage = 0.99865 × 100 = 99.865%
Approximately = 99.87%
Therefore, the percentage of babies would be at least 9.4 lbs = 99.87%

Aaron started at a height of 43 feet in the air. He jumped feet first from the cliff into the water below. The total
distance he traveled was 52 feet. How far underwater did Aaron travel?
Answer:
Aaron travelled about 9 feet underwater
Step-by-step explanation:
We need to work with the information we are given in the question.
there are two stages of Aaron's travel. the first distance was in the air, and the second distance was in the water.
We are given both the total distance travelled and the distance travelled in the air.
To get the distance travelled in water, we subtract the distance travelled in the air from the total distance.
This will be 52 feet - 43 feet = 9 feet
Hence Aaron travelled about 9 feet underwater

Pythagorean’s theorem
The upper-left coordinates on a rectangle are (-8,8)(−8,8)left parenthesis, minus, 8, comma, 8, right parenthesis, and the upper-right coordinates are (-3,8)(−3,8)left parenthesis, minus, 3, comma, 8, right parenthesis. The rectangle has an area of 151515 square units.
Draw the rectangle on the coordinate plane below.
Answer:
The other two co-ordinates are (-3, 5) and (-8, 5).
Step-by-step explanation:
Consider the rectangle ABCD.
A = upper-left coordinates = (-8, 8)
B = upper-right coordinates = (-3, 8)
C = lower-left coordinates
D = lower-right coordinates
Let the side AB form the length of the rectangle.
Compute the distance between the points A and B as follows:
[tex]AB=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
[tex]=\sqrt{(-3+8)^{2}+(8-8)^{2}}\\=\sqrt{(5)^{2}}\\=5[/tex]
The length of the rectangle ABCD is 5 units.
The are of ABCD is given as 15 square units.
Compute the breadth of the rectangle as follows:
[tex]\text{Area}=\text{l}\times\text{b}\\15=5\times\text{b}\\b=3[/tex]
So, the breadth of the rectangle is 3 units.
Then from point B, 3 units below would be (-3, 5).
And from point A, 3 units below would be (-8, 5).
The rectangle on the coordinate plane is attached below.

Hodel just got her driver's license. Her parents offer her two options. 1. They'll buy her a used car that will cost her $0.50 per mile in gas and maintenance fees. 2. They'll buy her a new hybrid car but she'll have to contribute $5,000 to the cost. The new car will then cost her an additional $0.10 per mile in gas and maintenance fees. If she plans to keep the car until she graduates from college in six years and she intends to drive it 10,000 miles each year, which option will cost her less?
Answer:
The second option will cost her less than the first one.
Step-by-step explanation:
In order to solve this problem we will create two functions to represent the cost of the car in function of the miles drove by her.
For the first option we have:
[tex]cost_1(x) = 0.5*x[/tex]
For the second option we have:
[tex]cost_2(x) = 5000 + 0.1*x[/tex]
Since she intends to drive it for 10,000 miles per year for 6 years, then the total mileage she intends to drive her car is 60,000 miles. Applying this to the formula of each car and we have:
[tex]cost_1(60000) = 0.5*60000 = 30000[/tex]
[tex]cost_2(60000) = 5000 + 60000*0.1 = 11000[/tex]
The second option will cost her less than the first one.
