Answer:

B. 34

Bonus: x is 94.

Step-by-step explanation:

Looking at the picture, the 112-degree angle is supplementary (180 degrees total) to the 2y angle. As a result, we can form the equation: 112 + 2y = 180.

112 + 2y = 180

<em>First, subtract 112 from both sides.</em>

2y = 180 - 112

2y = 68

<em>Then divide both sides by 2.</em>

y = 68/2

y = 34

Bonus:

x + 18 is vertical to 112, so the equation x + 18 = 112 will be used.

x + 18 = 112

<em>Simply subtract 18 from both sides.</em>

x = 112 - 18

x = 94

Stells [14]

<h2>Answer:</h2>

The number of scoops of oatmeal he will need for the recipe is:

21 scoops.

<h2>Step-by-step explanation:</h2>

It is given that:

Beaus recipe for granola bars calls for 3 1/2 cups of oatmeal.

i.e. the cups of oatmeal required is:

$3\dfrac{1}{2}\ cups=\dfrac{3\times 2+1}{2}\ cups$

i.e.

$\dfrac{7}{2}\ \text{cups\ of\ oatmeal\ is\ required}$

Also, he has:

$\dfrac{1}{6}\ \text{cup scoop}$

This means that:

$\text{Number of scoops of oatmeal he need}=\dfrac{\text{Number of cups of oatmeal}}{\text{Number of cup scoop he has}}\\\\i.e.\\\\\text{Number of scoops of oatmeal he need}=\dfrac{\dfrac{7}{2}}{\dfrac{1}{6}}\\\\i.e.\\\\\text{Number of scoops of oatmeal he need}=\dfrac{7\times 6}{1\times 2}\\\\i.e.\\\\\text{Number of scoops of oatmeal he need}=21\ \text{scoops}$
