Sara earns $80.50 for 7 hours of pet sitting. She earns the same amount per hour each time she pet sits. How many hours does Sara need to pet
sit to earn $138?
A 12 hours
B 14 hours
20 hours
D 23 hours

A.) 12 Hours

Step-by-step explanation:

80.50 ÷ 7 = 11.5

138 ÷ 11.5 = 12

here the number -5 is all of the following except a rational number.

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
