Which equation will you solve this problem? each boxcar in a toy train is the same length. there are 3 boxcars. their total length is 21 inches. how long is each boxcar?

i dont know

step-by-step explanation:

umm. i dont know

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
