15 to the 2nd power or 15 squared equals 15 * 15 which equals 225.

y = x/k so 15 = 6/k making k = 0.4. when x = 10 y = 10/0.4 ie 25 alternatively y/x = k ie 15/6 = k so k = 2.5; y/10 = 2.5 making y = 25.

y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.

y = 3x y = 3*19 = 57

The phrase "varies directly as" means that there is a number k such that w = k(2x - 1). From the results given for w = 9 when x = 2, 9 = k(4 - 1), or k = 3. Then when w is 15, 15 = 3(2x - 1), or 15 = 6x - 3, or 6x = 15 + 3, or x = 18/6 = 3.

No.

First, find 15% of 2037.00, by doing (2037*0.15), which equals 305.55; then subtract this 15% amount from 2037, so (2037-305.55) which equals 1731.45.

15 to the 2nd power or 15 squared equals 15 * 15 which equals 225.
