Answer:
The answer to your question is below.
Step-by-step explanation:
14.- Use proportions to solve these problems.
[tex]\frac{x + 6}{10} = \frac{x + 9}{14}[/tex]
14(x + 6) = 10(x + 9)
14x + 84 = 10x + 90
14x - 10x = 90 - 84
4x = 6
x = 6/4
x = 3/2
15.- [tex]\frac{x - 1}{8} = \frac{x + 2}{10}[/tex]
10(x - 1) = 8(x + 2)
10x - 10 = 8x + 16
10x - 8x = 16 + 10
2x = 26
x = 26 / 2
x = 13
16.- [tex]\frac{x + 1}{9} = \frac{10/3}{5}[/tex]
5(x + 1) = 9(10/3)
5x + 5 = 30
5x = 30 - 5
5x = 25
x = 25 / 5
x = 5
