Mrs. walters drove 360 miles on 25 gallons of gas. mr. walters drove 480 miles on 32 gallons of gas.

a. find the mileage per gallon for mrs. walters's car.
b. find the mileage per gallon for mr. walters's car.
c. which car is getting the better mileage per gallon?

explain your answer

a-14.4 mpg

b-15 mpg

c-the second car

Step-by-step explanation:

All you have to do is divide miles by gallons

360/25 = 14.4

480/32 = 15

The higher the value the better mileage so the second car has better mpg

it is part of the rising action that reveals public sentiment toward hester.

explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
