Question

Suppose x varies directly with y and inversely with z. If x=14 when y=49 and z=7, then what is x when y=18 and z=6?

Answer 1

Answer:

6

Step-by-step explanation:

x varies directly with y and inversely with z:

x = ky/z

x = 14 when y = 49 and z = 7.

14 = k (49)/(7)

k = 2

When y = 18 and z = 6:

x = 2 (18)/(6)

x = 6
