Gabrielle's age is three times mikhail's age. the sum of their ages is 32 . what is mikhail's age?

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

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
