A rain gutter along the edge of a roof has the shape of a rectangular prism. It is 7 inches7 inches high and 18 feet18 feet long. It has a volume of 7 , 560 cubic inches.7,560 cubic inches. How wide is the gutter?

w = 5 inches is the width of the gutter

Step-by-step explanation:

Change 18 ft to inches: 12 * 18 = 216

let w = the width of the gutter

the volume equation:

216 * 7 * w = 7560

1512w = 7560

w = 7560/1512

w = 5 inches is the width of the gutter

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
