1. Describe the sequence of transformations from
rectangle ABCD to A'B'C'D',
DU
A
D

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

you probably already have the answer but anyways it's b. 15.0
