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
