a proportion is an equality between two ratios. x equals 5y-c is not a ratio, so it cannot be proportional.
Yes. It is inversely proportional. An increase in x results in a proportional decrease in y and vice versa.
Various options: y is directly proportional to k, with x as the constant of proportionality; y is directly proportional to x, with k as the constant of proportionality; x is inversely proportional to k, with y as the constant of proportionality; x is directly proportional to y, with 1/k as the constant of proportionality; k is directly proportional to y, with 1/x as the constant of proportionality; and k is inversely proportional to x, with y as the constant of proportionality.

The Answers community requires more information for this question. Please edit your question to include more context. The answer will depend on the nature of proportionality between the two variables: is y directly proportional to x, or some power of x, is it inversely proportional?.
x isn't in the calculation so it cant be solved.

You need to know what is the relationship between x and y. Are they proportional? Inversely proportional? Several other options also exist.
Yes. It is inversely proportional. An increase in x results in a proportional decrease in y and vice versa.
Insufficient information. What is x when y = 12?
x5y2 - 2 = 0 ... makes sense
According to the equation [ y = 2x ], 'y' is directly proportional to 'x' .

i think it would be like this: 4:25 :: 1:6.25
y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.
