Determine the equation of combined, then solve for the missing value.

Variation x varies directly with y and z.
x=5 when y=10 and z=5. find x when y=20 and z=10

  • ALGEBRA 1 - ,

    "x varies directly with y and z" ---> x = k(yz), where k is a constant

    given: when x=5, y = 10 and z = 5
    5 = k(10)(5)
    50k = 5
    k = 1/10

    then x = (1/10)yz
    for y=20, z=10
    x = (1/10)(20(10) = 20
