    10 because if you divide 12 by 3 it will give you 4 x=4 and 3 by itself and you would get y=1 in order to get 40 you will have to multiple for by 10 and multiply y by 10

    y varies directly with x

    so y = kx

    y = 3 when x = 12 then 3 = 12k so k = 3/12 = 1/4

    If x = 40 then

    y = kx

    y = 1/4 (40)

    y = 10

    Answer

    y = 10 when x = 40
