Answer:
The equation is 19+3.5h=10+4.75h. The answer is 7.2 hours.
Explanation:
The equation for this problem would be 19+3.5h=10+4.75h. All you have to do is find h. So subtract 3.5h from both sides and 10 from both sides. You will get the equation 1.25h=9. Divide 1.25 from both sides and you will end up with h=7.2 hours.
