The square of a number decreased by 15 is equal to twice the number. find the number

18.75 gallons

step-by-step explanation:

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

- (2, -7)

- lines r and s and lines t and u must be parallel
