You are preparing to tile a rectangular room that is 15 1/2 feet by 18 1/2 feet in size. the tiles are square measuring 12 inches on each side, and are sold in boxes that contain enough tile to cover 25 sqaure feet. how many boxes of tile must you order to complete the job.
a.11
b.12
c.34
d.59
e.287

Find the area of the room by multiplying the length by the width:

Area of room = 15.5 x 18.5 = 286.75 square feet.

Divide the total area of the room by the area of a box to find the number of boxes needed.

286.75 / 25 = 11.47

Since you can't buy a partial box, round up to the nearest whole number.

You need B. 12 boxes total.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

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
