Answer: x = 36, y = 10, and z = -25

Step-by-step explanation:

99 and -3z +6 are same side interior angles, so they sum to 180 degrees.

99 -3z + 6 = 180

-3z = 75

z = -25

Opposite angles of a parallelogram are congruent

2x + 9 = -3x + 6

2x + 9 = 75 + 6

2x = 81 - 9

2x = 72

x = 36

9y + 9 = 99

9y = 90

y = 10

According to definition of parallelogram

  • opposite sides and angles are equal

  • Consecutive sides have sum 180°

\\ \rm\hookrightarrow 2x+9+99=180

\\ \rm\hookrightarrow 2x+108=180

\\ \rm\hookrightarrow 2x=72

\\ \rm\hookrightarrow x=36

  • 2x+9=72+9=81

And

  • -3z+6=81
  • -3z=75
  • z=-25

And

  • 9y+9=99
  • 9y=90
  • y=10

2/3 cup of oatmeal - 10 granola bars

When the number of cups of oatmeal increases, the number of granola bars also increases.
If you use for example twice as many cups of oatmeal, you'll make twice as many granola bars.
Therefore, the first step is to calculate how many times 20 cups of oatmeal is more than 2/3 cup of oatmeal. To do it, divide 20 by 2/3.

20 \div \frac{2}{3} = 20 \times \frac{3}{2}=\frac{60}{2}=30

You have 30 times as many cups of oatmeal, so you'll make 30 times as many granola bars.

10 \times 30= 300

300 granola bars can be made with 20 cups of oatmeal.
