Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.

w = ±√55+4

Step-by-step explanation:

the diameter is 16 cm. are you a teacher?

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
