The total cost to five boxes of pasta is $13. There are 12 ounces of pasta in each box. Each box of pasta cost the same amount.
vodomira [7]

Answer:

She can buy 25 boxes of pasta with $65

Step-by-step explanation:

This question is actually very easy if you forget about all of the unnecessary information. They throw a lot of unnecessary information like they telling you that there are 12 ounces of pasta in each box. You never need that information. My point is that watch out for unnecessary info. Other than that, you can simply multiply 13 (price of 5 boxes) by 5 and get 65. That means that just multiply 5 by 5 and you will see that she can buy 25 boxes of pasta with $65.

If L is parallel to M, find the value of each missing variable(s)
nevsk [136]

Answer:

5. x = 13

6. x = 11; y = 3

Step-by-step explanation:

5. (9x + 2)° = 119° (alternate interior angles are congruent)

9x + 2 = 119

Subtract 2 from each side

9x + 2 - 2 = 119 - 2

9x = 117

Divide both sides by 9

\frac{9x}{9} = \frac{117}{9}

x = 13

6. (9x + 25)° = (13x - 19)° (corresponding angles are congruent)

9x + 25 = 13x - 19

Collect like terms

9x - 13x = - 25 - 19

-4x = -44

Divide both sides by -4

\frac{-4x}{-4} = \frac{-44}{-4}

x = 11

(13x - 19)° + (17y + 5)° = 180° (linear pair)

13x - 19 + 17y + 5 = 180

Plug in the value of x and solve for y

13(11) - 19 + 17y + 5 = 180

143 - 19 + 17y + 5 = 180

Collect like terms

129 + 17y = 180

Subtract 129 from both sides

129 + 17y - 129 = 180 - 129

17y = 51

Divide both sides by 17

\frac{17y}{17} = \frac{51}{17}

y = 3
