Question

2 X varies directly as 3 Y and X is equals to 3 when Y is equals to 4 find Y when X is equals to 10​

Answer 1

Answer:

Step-by-step explanation:

let 2x directly varies with 3y i.e 2x = p3y  so if x=3 then y = 4  so then p = 6/12 = 1/2 so 2x=6/12 3y given x=10 so substitute 20 = 6/12 3y    3y = 20 . 2 = 40            

3y=40      y=40/3
