13: multiply the amount by the tax rate (to make a percent a decimal move the decimal point 2 places to the left) and add the original amount and the taxed amount together. For 12 do above but then multiply the total by the tip rate and add together (basically the same as the tax again) :) I hope this helps

Answer:

The answer to your question is below.

Step-by-step explanation:

14.- Use proportions to solve these problems.

$\frac{x + 6}{10} = \frac{x + 9}{14}$

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

14x + 84 = 10x + 90

14x - 10x = 90 - 84

4x = 6

x = 6/4

x = 3/2

15.- $\frac{x - 1}{8} = \frac{x + 2}{10}$

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

10x - 10 = 8x + 16

10x - 8x = 16 + 10

2x = 26

x = 26 / 2

x = 13

16.- $\frac{x + 1}{9} = \frac{10/3}{5}$

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

5x + 5 = 30

5x = 30 - 5

5x = 25

x = 25 / 5

x = 5
