Hi what is the answer

y = 5x

y = 60 when x =12

Step-by-step explanation:

Directly proportional means

y = kx where k is the constant of proportionality

We know y and k so we can find k

30 = k*6

Divide each side by 6

30/6 = 6k/6

5 =k

The equation is

y = 5x

We can find y when x=12

y = 5*12

y = 60

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

i think that you should ask google for the answer to that problem because if we don't know it google does
