Help please will mark!! Melissa the trainer has two solo workout plans that she offers her clients: Plan A and Plan B. Each clie
ioda

Answer:

3

clients who did Plan A and

2

who did Plan B. On Tuesday there were

8

clients who did Plan A and

4

who did Plan B. Linda trained her Monday clients for a total of

4

hours and her Tuesday clients for a total of

9

hours.

Step-by-step explanation:

let x equal the number of hours for each plan A workout.

let y equal the number of hours for each plan B workout.

on monday, there were 3 clients who did plan A workout and 2 clients who did plan B workout for a total of 4 hours.

the formula for monday becomes 3x + 2y = 4

on tuesday, there were 8 clients who did plan A workout and 4 clients who did plan B workout for a total of 9 hours.

the formula for tuesday becomes 8x + 4y = 9

you have to solve these 2 equations simultaneously.

they are:

3x + 2y = 4

8x + 4y = 9

multiply both sides of the first equation by 2 and leave the second equation as is to get:

6x + 4y = 8

8x + 4y = 9

In triangle ABC, the length of side AB is 19 inches and the length of side BC is 28 inches. Which of the following could be the
DENIUS [597]
<h3>Answer:  C) 42 inches</h3>

=========================================================

Explanation:

Let's say we have a triangle with sides x,y,z

Also, let's further say we know that x = 19 and y = 28 (from AB and BC respectively).

The third missing side z can't be nailed down to a single number, but we can establish a possible range. That range is

y-x < z < y+x

28-19 < z < 28+19

9 < z < 47

So any number between 9 and 47, excluding both endpoints, will work as a possible side length for the third missing side.

Something like 7 inches is too small, so we rule out choice B. Choice D is ruled out since 49 inches is too big. Same goes for choice A also.

The only thing left is choice C. The 42 is between 9 and 47

In other words, 9 < 42 < 47 is true.

So that's why the third missing side could be 42 inches.

Side note: I'm using a modification of the triangle inequality theorem.
