A personal trainer designs exercise plans based on a combination of strength-training and aerobic exercise. A beginner plan has

Korvikt [17]

"Each plan utilizes a combination of 2 strength-training sessions and 2 aerobic exercise sessions per week." because.
Let n be the number of aerobic and strength-training exercises per week.
Let x be the number of strength-training exercises per week on the beginner

15x + 20n = 90

Let y be the number of strength-training exercises for week on the advanced plan.
20y + 30n = 130

Multiply both sides by 1.5, to get:
22.5x + 30n = 135
Subtracting equation 2 from 3 we get:
22.5x - 20y = 5

Step 1:

In this question, we are given the following:

What is the midpoint of a line segment with the endpoints (-4,-3) and (7,-5)?

A. (-3.5, 1)

B. (1.5,-4)

C. (-4,1.5)

D. (1.-3.5)

Step 2:

The midpoint of a line segment with the endpoints (-4,-3) and (7,-5) is:

$\begin{gathered} (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}) \\ =\text{ (}\frac{-4+7}{2},\frac{-3+(-5)}{2}) \\ =\text{ (}\frac{3}{2},\frac{-8}{2}) \\ \end{gathered}$
