Answer:
477
Step-by-step explanation:
It's pretty simple. All you need to calculate is how much they made in the 9 hours. So multiply 58 x 9 and you get 522. Then take away what they didnt make, which was 45. That gives you 477.
Answer:
so to factor out you find the greatest common factor of 14 and 7
if you have 2x-2 then you can factor out the 2 and get 2(x-1)
7=7*1
14=2*7
the greatest common factor is 7
14x-7=7(2x-1)
