Which is the best equation to use to solve this problem? the perimeter of a rectangle is 90 ft. the ratio of the length to the width is 8: 7. what are the dimensions of the rectangle?
a. 8x+7x=90
b.8x+8x+7x+7x=90
c.8x/7x=90
d.2x+2x=90

b, i believe, but not sure.

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

lol.

it's ok we all do this sometimes.
