140

Step-by-step explanation:

AEF and DFE are opposite interior angles, so they are equal to each other

you can set the equation to 2x + 60 = 3x + 20

subtract 2x from both sides: 60 = x + 20

subtract 20 from both sides: 40 = x

plug in the value of x to the equation for AEF: 2(40) + 60

you get AEF is 140

b and c

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
