Helena uploaded 520 more video files than photo files. Helena uploaded 65 fewer video files than photo files. Helena uploaded 9 times as many photo files as video files.

Answer 1

Helena uploaded 9 times as many photo files as video files

65 * 9 = 585

have a great day :)

Answer 2

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
