The common factors of 4, 20, and 24 are 1, 2, and 4 First find the factors that go into the numbers The factors of 4 are 1, 2, and 4 The factors of 20 are 1, 2, 4, 5, 10, and 20 The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24 Then find the factors that match: The common factors are: 1, 2, 4.
We note that 8 = 4 x 2' So 4 x 7 = 28 So mulktply 28 by '2' Hence 28 x 2 = 56 The answer!!!!!
4 and 4 2 and 8
The percent of 2,000,00 and 4,000,000 would be 2% and 4%. This is used in math.
2 x 2 x 2 x 2 2 x 8 4 x 4

y is 12
2=8/4 the constant is 8 y-k/x i think.
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 varies inversely as x2 so y = c/x2 for some constant c. When x = 5, y = 4 So c = x2y = 100 that is y = 100/x2 Then, when x = 2, y = 100/4 = 25
xy = 8 or y = 8/x
z = 8/3.
y varies as 1/x^(2) y = k X 1/^(2) y = k/x^(2) k = y x^(2) When y = 4 & x = 3 Then k = 4(3^(2)) k = 4(9) k = 36 (The constant of proportionality Hence the general equation is y = 36/x^(2) When x = 2 y = 36/2^(2) y = 36 /4 y = 9 The answer!!!!!
If y varies directly as x and if x = 2 when y = 8 then k = 4.
f(2) = 24.
