y varies directly as x
y=kx, where k is any constant
y = 4 when x=-2
4 = k (-2)
4 =-2k
k=-2
Therefore, y=-2x
When x=30
y = -2(30) = -60

X varies directly with y and inversely with z x equals 20 when y equals 8 and z equals 4 Find x when y equals 4 and z equals 8?
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.
X varies directly with y and z x equals 40 when y equals 10 and z equals 20 Find x when y equals 30 and z equals 40?

If x varies jointly as y and the square as z and x equals 40 when y equals 20 and z equals 2 find x when y equals 30 and z equals 3?
As x ∝ yz2 then x = kyz2 where k is a constant. Substituting the given figures, 40 = k*20*22 = 80k Then k = ½ and the formula is, x = ½yz2 So, x = ½ * 30 *32 = 135
Do you have to regroup 34 plus 9 equals?
If you mean adding in groups, I suppose you could break 34 into 30 and 4. Then you could add 9 to 4 to get 12, and then perhaps more easily add 13 and 30 to get 43.
