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

On a recent trip to the convenience​ store, you picked up 4 gallons of​ milk, 5 bottles of​ water, and 8 ​snack-size bags of chi
Otrada [13]

Answer:

One gallon of milk costs $3.64

One  bottle of water costs $2.54

One bag of chips costs $0.79

Step-by-step explanation:

m represent gallons of milk

w represents  bottles of water

c represents snack-size bags of chips

t = total bill

t = m + w + c         ... eq 1

t = $33.60

but

w = 2c

m = 1.90 + w

m = 1.9 + 2c

Slot in the values in eq 1

33.60 = (1.9 + 2c ) + 2c + c

33.60 = 1.9 + 5c

33.60 - 1.9 = 5c

31.7 = 5c

c = $6.34

Slot in the value of c in w and m

w = 2c

w = 2(6.34)

w = $12.68

m = 1.9 + 2c

m = 1.9 + 2(6.34)

m = $14.58

4 gallons of milk cost $14.58

Therefore, one gallon if milk costs = 14.58/4 = $3.64

5 bottles of water cost $12.68

Therefore, one bottle of water costs = 12.68/5 = $2.54

8 bags of chips = $6.34

Therefore, one bag of chips cost = 6.34/8 = $0.79
