At what hour will the cost be the same?

The equation is 19+3.5h=10+4.75h. The answer is 7.2 hours.

Step-by-step 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.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
