Quizplus · Accepted Answer

The given information "y varies directly as x" can be written in the form of a proportionality constant like this: y=kx
Now we can substitute the given values for y and x to find the value of k:
36=k(6)
k=6
Therefore, our equation is y=6x
To find y when x is given, we simply substitute the value of x into this equation:
y=6(x)
y=6(18)
y=108
So the correct answer is D) 108.
