Answer:

x = 17 1/3

Step-by-step explanation:

Corresponding segments are proportional.

(3x)/(4x) = (3x +7)/(5x -8)

3(5x -8) = 4(3x +7) . . . . . . . . multiply by 4(5x-8)

15x -24 = 12x +28 . . . . . . eliminate parentheses

3x = 52 . . . . . . . . . . add 24-12x

x = 17 1/3 . . . . . . . . . divide by 3

Answer:

Greg worked more than 20 hours.

Step-by-step explanation:

Let's solve the inequality for $h$ so we know how many hours Greg worked:

Step 1. Subtract 25 from both sides of the inequality

$14h+25>305$

$14h+25-25>305-25$

$14h>280$

Step 2. Divide both sides by 14

$\frac{14h}{14} >\frac{280}{14}$

$h>20$

We can conclude that Greg worked more than 20 hours.
