If the best gas mileage is the highest rate, which truck has the best gas mileage?

a. truck a, because for every mile the truck uses 19 gallons.

b. truck a, because for every gallon the truck goes 19 miles.

c. truck b, because for every mile the truck uses 18 gallons.

d. truck b, because for every gallon the truck goes 18 miles.

A. Truck A , because of every mile the truck uses 19 gallons.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

unlimited solutions.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
