Answer:
36(z + 2)
Step-by-step explanation:
First, find the GCF or greatest common factor. The GCF is the largest factor that all the numbers share. Both 72 and 36 are divisible by 36. 72 ÷ 36 = 2 and 36 ÷ 36 = 1. So, the factoring would look like 36(1z + 2) or 36 (z + 2)
This you answer x=-1/5y+-4/5

The answer to your question is A
You're on the right track. If they generated 380 less than 2012, then in 2013 they generated 9782-380 = 9402.
They used 10472 in 2012, so 10472+390 = 10862 used in 2013. now subtract used from produced to see how much they had to buy...
10862-10472 = 390
They had to buy 390khW from the power company.
Example:
5/20 x 100 you put whatever fraction your looking for into calculator and multiply by 100
