<h3>Answer: Choice B</h3>

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

Explanation:

Here's a slightly more detailed breakdown of what's going on

3x + 2y = 15 ... start with the first equation

3x + 2( y ) = 15 .... the parenthesis don't change the expression

3x + 2( 3x+5) = 15 ... replace y with 3x+5; since y = 3x+5

From here, you solve for x like you would any other single variable equation. Once you know x, you can determine y through y = 3x+5.

What is the algebraic expression that describes the monthly pay? Let x be the hours of training.
Radda [10]
For every 10 hours of training, monthly pay increases by 100
that means that for every 1 hour, monthly pay increases by 10
so the answer must be in the form 10x + something
let's take the 1st row in the table:
10 hours of training = 1300 monthly pay
10x+ something = 1300
10*10 + something=1300
something = 1200
therefore, monthly pay = <span>A. 10x+1200 </span>
