Answer:
Step-by-step explanation:
x=2
so 7*2= 14
therefore the answer is 14
80 × .65 = 52
She completed 52 serves.
Easy!
Since the greatest multiple of 9 lesser than 79 is 72, you get a remainder of 7
8 7/9
You will set it up so that the two equations are equal to each other.
2,200 * (2.31 * 10^x) = 1.05 * 10^y
Then depending on what you have learned you either plug in each value and check, or solve it mathmatically.
The steps for solving mathmatically:
Distribute the 2,200.
5082 * 22000^x = 1.05 * 10^y
Next divide both sides by 1.05
4840 * 20952.4^x = 10^y
I don't know if that is to the power of y or times y?
Multiply everything to get 90, because for every option, you multiply that one with the other.
