10 + 2x

x = 4

Step-by-step explanation:

The quadrilateral is a rectangle and opposite sides are congruent, hence

10 + 2x = 18 ( subtract 10 from both sides )

2x = 8 ( divide both sides by 2 )

x = 4

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

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
