Answer:each session of body sculpting workouts burns 51 calories.

Each session of Yoga workouts burns 83 calories.

Step-by-step explanation:

Let x represent the number of calories that she burnt doing one body sculpting workout session.

Let x represent the number of calories that she burnt doing one Yoga session.

Last week, she burned a total of 517 calories by doing 2 body sculpting workouts and 5 yoga sessions. This means that

2x + 5y = 517 - - - - - - - - - -1

This week, she has completed 2 body sculpting workouts and 1 yoga session and burned a total of 185 calories. This means that

2x + y = 185 - - - - - - - - - - - - 2

Subtracting equation 2 from equation 1, it becomes

4y = 332

y = 332/4 = 83 calories

Substituting y = 83 into equation 2, it becomes

2x + 83 = 185

2x = 185 - 83 = 102

x = 102/2 = 51 calories

Given the points A(-3, -2) and B(6, 1), determine the coordinates of point P on directed line segment that partitions in the rat

serg [7]

Answer:

$P = (3,0)$

Step-by-step explanation:

Given

$A = (-3,-2)$ ---- $(x_1,y_1)$

$B = (6,1)$ --- $(x_2,y_2)$

$m:n =2:1$

Required

The coordinates of P

This is calculated as:

$P = (\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n}]$

So:

$P = (\frac{2*6+1*-3}{2+1},\frac{2*1+1*-2}{2+1})$

$P = (\frac{9}{3},\frac{0}{3})$

$P = (3,0)$
