A/4 = 8/16
cross multiply
(16)(A) = (8)(4)
16A = 32
A = 32/16
A = 2
25% is equal to 1/4 so that means 90 is 1 out of 4 peaces of that number so you are ganna want to multiplay 90 X 4 to get your answer
It’s not that hard all u need to do is when u multiply it just multiply it. For example what’s 2/3x4/3=8/3 and that is just 8/3 but when the denominator is different u just multiply it it’s not that hard
Adding 2x to both sides we get
y = 2x
This is direct variation where the constant is 2.
