Question

Y is directly proportional to x when y =30 x = 6

Answer 1

a) y=kx (equation/formula)

b) step 1 find constant K
y=kx
30=k(6)
k= 5

step 2 use formula and Constant value K
y=kx
y= 5(12)
y=60
final answer= 60

Answer 2

Answer:

a) 5x = y

b) 5 (12) = 60

Step-by-step explanation:

a) 5x = y when x is 6 y is 30

   5(6) = 39

b) 5 (12) = 60
