Acircle with a radius of 4 in, is dilated by a scale factor of 5. what will be the circumference of the circle after dilation?
21 in
4 in
161 in
24 in

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

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
