x = 2(x+2) + 3(x-1) = 3x + 7

2x + 4 + 3x -3 = 3x + 7

2x + 3x - 3x = 7 - 4 + 3  

2x = 6

x = 3

You can rent time on computers at the local copy center for a $7 setup charge and an additional $1.75 for every 5 minutes. How m
Vera_Pavlovna [14]

For 46 minutes you can use the computer for $23.

Given that, you can rent time on computers at the local copy centre for a $7 setup charge and an additional $1.75 for every 5 minutes.

We need to find how much time can be rented for $23.

<h3>What is a linear equation?</h3>

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.

Now, every minute charge=1.75/5=$0.35

Let time used be t, so we can write an equation as

7+0.35t=23

Solve the equation for t.

That is, 0.35t=16

⇒t=16/0.35=45.714

⇒t=45.714≈46 minutes

Therefore, for 46 minutes you can use the computer for $23.
