A) x + y = 17
B) x - y = 27
Adding both equations:2x = 44
x = 22
y = -5
She should use 13 factors.
All 13 factors are the same thing . . . 7 .
7^13 should be written as 7¹³ .
It means: 7·7·7 · 7·7·7 · 7·7·7 · 7·7·7 · 7
It's the first one. y = 3x
proportional means they are just some multiple of the other.
