Answers

Answer: m=−3

Step-by-step explanation: −40−2(3m+1/2)=7m−2

−40+(−2)(3m)+(−2)(1/2)=7m+−2

−40+−6m+−1=7m+−2

(−6m)+(−40+−1)=7m−2

−6m+−41=7m−2

−6m−41−7m=7m−2−7m

−13m−41+41=−2+41

−13m/−13=39/−13

m=−3

What mistake I guess Keith did make is he subtracted 2 from -39 which equaled to -37 which caused him divide -37 by 13 when it should have been 39 divided by 13 because he should have left 39 alone and not have subtracted 2 from it also it should not have been negative basically what I'm trying to say is that he did his division and subtraction wrong.

 

m = -3, hope it was helpful! :)

1. The distance that Giselle can run is a function of the amount of the time she speeds running. Giselle runs 3 miles in 21 minutes. Assume she runs at a constant rate.
a. Write an equation in two variables that represents her distance run, y, as a function of the time, x, she spends running

b. Use the equation you wrote in part (a) to determine how many miles Giselle can run in 14 minutes.

c. Use the equation you wrote in part (a) to determine how many miles Giselle can run in 28 minutes.

d. Use the equation you wrote in part (a) to determine how many miles Giselle can run in 7 minutes ​

Answers

Answer: 150 pounds

Step-by-step explanation:

Let the the astronaut weight on Earth be represented by x.

Based on the information given in the question, thus can be formed into an equation as:

16.5% of x = 24.75

16.5% × x = 24.75

16.5/100 × x = 24.75

0.165x = 24.75

x = 24.75/0.165

x = 150 pounds

The astronaut weigh 150 pounds on Earth.

Gina takes three hours of dance classes for x weeks. Which expression shows the number of hours Gina dances?
x - 3
x + 3
3x
x ÷ 3

Answers

Answer:

x = number of weeks.

When you plug in the number of weeks for x you'll get the amount of hours she had for dance classes.

Example: She has been doing classes for 3 weeks, how many hours did she do?

3x

3(3)

= 9(She had 9 hours of dance class combined for the past three weeks).

Ali can bake 105 cookies in 3 hours. At that rate, how many cookies can she bake in 5 hours?

Answers

so first you find out how many she can bake in 1 hour so you divide 105 and 3 which is 35

so since she bakes 35 cookies and hour you multiply 35 by how many hours she cooks

so 35 x 3 =105                    35 x 5=175

Ali cooks 175 cookies in 5 hours

175 cookies is the correct answer105 ÷ 3 = 3535 x 5 = 175Please let me know if I am wrong.

Answers

Answer:

y = (3/-2)x + 4.

Step-by-step explanation:

slope intercept form is y = mx + b

1. Lets first look for the y intercept (b). On the graph the line intercepts the y axis at 4. 4 is our b.

2. To find the slope (m) remember rise over run. Counting from lower dot, it goes up 3 and left 2. 3/-2. The two is negative because it is decreasing (towards the left of the graph).

3. Now plug the numbers into slope intercept form. y = (3/-2)x + 4.
