P + v = 650....p = 650 - v
4p + 9v = 2925
4(650 - v) + 9v = 2925
2600 - 4v + 9v = 2925
-4v + 9v = 2925 - 2600
5v = 325
v = 325/5
v = 65.....video files
p + v = 650
p + 65 = 650
p = 650 - 65
p = 585....photo files
answer : Helena uploaded 9 times as many photo files as video files
65 * 9 = 585
What do we do? Is there a attachment?
Remember to do PEMDAS so your answer is not correct, since you multiplied before doing the parentheses/exponents.

= 3(9) - 5(4)
= 27 - 20 = 7
