The answer is 3,464 i know this because 17X3=51 204X17=3,464

Cora · Answer 2

Determine the constant of proportionality: Start with the generic form y = kx (for direct proportion). Insert the given info to find the value of k:

51 = k (3), so that k = 17. Then the rule here is y = 17x.

Now, if y is 204, 204 = 17x, and x = 204/17 = 12

Summary: When y = 204, x = 12.
