Hello I wanted to review this with my daughter but I want to make sure I'm understanding your steps. I am trying to find the indicated length for LM, see attachment
So X + 2X = 18
3X = 18
X = 6
LM = 2X
LM = 2 * 6
LM = 12?

your answer would be 12

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
