Given x=k1y and x=k2/z
x=125 ,y=5 then k1=25
x=125 , z=4 then k2=125(4)=500
If y=4 ,z=5 then x=25y = 100

x = 24
y is 12
y = cx when x = 8, y = 12 so that 12 = 8c which gives c = 12/8 = 1.5
y=kx^2 hence k=198/36. now y=198/36*(2)^2 y=22

m = 24
x = 24

y is 12
The answer is x=10. If: x=20 y=8 z=4 then: y=8/2=4 z=4*2=8 since x varies directly with y, meaning whatever happens to y, happens to x, so if y was divided by 2, then x should be divided by 2. After all, the inverse of division is multiplication.
y=(320 x 25 )/ 40 = 200.
