Answer 2

The answer to your question is below.

Explanation:

14.- Use proportions to solve these problems.

`(x + 6)/(10) = (x + 9)/(14)`

14(x + 6) = 10(x + 9)

14x + 84 = 10x + 90

14x - 10x = 90 - 84

4x = 6

x = 6/4

x = 3/2

15.-
`(x - 1)/(8) = (x + 2)/(10)`

10(x - 1) = 8(x + 2)

10x - 10 = 8x + 16

10x - 8x = 16 + 10

2x = 26

x = 26 / 2

x = 13

16.-
`(x + 1)/(9) = (10/3)/(5)`

5(x + 1) = 9(10/3)

5x + 5 = 30

5x = 30 - 5

5x = 25

x = 25 / 5

x = 5
