Find the measure of CDE. The measure of CDE equals a certain # of degrees.

2x-13+3x-8+2x-3+2x-7+3x-1+2x+11+2x+9= (7-2)×180

16x-12=(7-2)×180

(7-2)×180 Work this out on a calculator

And then that answer=16x-12

Then you solve by adding 12 both sides and dividing by 16 both sides to get what x is.

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
