Question

help!!! please!! y varies directly as x and inversely as z. find the variation constant K and the equation of variationz when y=50, x=20, and z=4.

Answer 1

k = 10

Explanation:

y = K x/z

y = 50

x = 20

z = 4

k = ?

50 = k * 20 / 4 Divide 20 by 5

50 = k * 5 Divide both sides by 5

50 / 5 = k * 5/5 Do the division

10 = k Switch

k = 10
