8/9=?/36 15:18=5:? ? to 7 = 9 to 21

Problem 1

Work Shown:

8/9 = x/36

36*8 = 9x

288 = 9x

9x = 288

x = 288/9

x = 32

Problem 2

Work Shown:

15:18 = 5:x

15/18 = 5/x

15x = 18*5

15x = 90

x = 90/15

x = 6

Problem 3

Work Shown:

x to 7 = 9 to 21

x/7 = 9/21

21x = 7*9

21x = 63

x = 63/21

x = 3

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
