erin rented a stand-up paddle board (SUP) while on vacation. She paid an initial rental fee of $15 and then $8.50 per hour. If she paid a total of $49.00, how many hours did she rent the SUP?

4

Step-by-step explanation:

1) for several hours she paid 49-15=34 USD;

2) if the price is 8.5 USD/hour, then the required time is: 34/8.5=4 hours.

Step-by-step explanation:

The equation to show the total charge:

Substitute 49 into equation and solve for h:

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
