The gym teacher has $250 to spend on volleyball equipment. She buys 4 volleyball nets for $28 each. Volleyballs cost $7 each. How many volley balls can she buy
Answer:
she can buy maximum of 19 balls.
Step-by-step explanation:
Let the number of volleyballs be x
we know that
![\text{(The cost of each volleyball net} \times \text{number of volleyball net)}+\text{(the cost of each volleyball} \times \text{number of volleyballs)}\leq \ 250](https://tex.z-dn.net/?f=%5Ctext%7B%28The%20cost%20of%20each%20volleyball%20net%7D%20%5Ctimes%20%5Ctext%7Bnumber%20of%20volleyball%20net%29%7D%2B%5Ctext%7B%28the%20cost%20of%20each%20volleyball%7D%20%5Ctimes%20%5Ctext%7Bnumber%20of%20volleyballs%29%7D%5Cleq%20%5C%20250)
so substituting the values,
![28(4) + 7x \leq 250](https://tex.z-dn.net/?f=28%284%29%20%2B%207x%20%5Cleq%20250)
![112 + 7x \leq 250](https://tex.z-dn.net/?f=112%20%2B%207x%20%5Cleq%20250)
![7x \leq 250 - 112](https://tex.z-dn.net/?f=%207x%20%5Cleq%20250%20-%20112)
![7x \leq 138](https://tex.z-dn.net/?f=%207x%20%5Cleq%20138)
![x \leq \frac{138}{7}](https://tex.z-dn.net/?f=%20x%20%5Cleq%20%5Cfrac%7B138%7D%7B7%7D)
![x \leq 19.7](https://tex.z-dn.net/?f=%20x%20%5Cleq%2019.7)

Step-by-step explanation:
Counterclockwise is going left, so if you start at the top, 270 degrees left of a clock will result in the same as 90 degrees clockwise.
Answer:
12
Step-by-step explanation:
They are the same angle so they must be equal.
So, x+5 = 2x-7
5+7 = 2x-x
12 = x
