Charge of Ralph:

Charge = $24  + $33 per hour

Let the time worked be = x.

For x hours, the cost = 33*x = 33x

Charge = 24 + 33x

24 + 33x = 189

33x = 189 - 24

33x = 165

x = 165/33

x = 5

The job took 5 hours.

Solve the inequality for v.<br>3v-37&gt;-2(8-5v)<br>Simplify your answer as much as possible.​
Oksana_A [137]

Answer:

-3 >v

Step-by-step explanation:

3v-37>-2(8-5v)

Distribute

3v -37> -16 + 10v

Subtract 3 from each side

3v -3v -37> -16 + 10v-3v

-37 > -16 +7v

Add 16 to each side

-37 +16 > -16+16 +7v

-21 > 7v

Divide each side by 7

-21/7 >7v/7

-3 >v
