PLEASE HURRY.
Niki can drive her car 22 miles on each gallon. If niki drives m miles which expression the number of gallons used?

A:m-22
B:22m
C:22/m
D:m/22

M divided by 22 = total number of gallons used for the trip (m/22)

Step-by-step explanation:

Let's identify what we know:

1) Niki's car can do 22 miles per gallon (mpg)

So, what formula would we use to find out how many gallons were used if Niki drove m (number of miles) miles?

Well, let's pretend that Niki drove 154 miles! How would we solve it? Let's create a formula:

154/22 = number of gallons used

so, 154 is m!

m/22 = number of gallons used.

D is the correct answer! :)

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
