Question

if x varies inversely as v, and x = 35 when v = 3, find x when v=21

Answer 1

x= 35
when you say " x inversely as v" it looks like this
x = k/v wherein k is constant

Answer 2

since x = 35 and v = 3 we can use the x = k/v

Answer 3

\[35 = k/3\]

Answer 4

so your k =?

Answer 5

@catherinek

Answer 6

k = 105

Answer 7

so when v = 21
k =vx
105 = 21(x)

Answer 8

so your x would be equal to?
