Yvaries directly as x and y = 9 when x = 72

y =

Step-by-step explanation:

since y varies directly as x, then the equation relating them is

y = kx ← k is the constant of variation

to find k use the given condition y = 9 when x = 72

k = = = , hence

y = × x =

im not quite sure if this is right but i got 5.6 oisutuve

step-by-step explanation:

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
