y/x is a constant; so first of you can solve for this constant. y/x=6/-3, or y/x=-2
y/4=-2
y=-8
3
f = 54
xy = K so K = 21
To find the number that, when multiplied by 3, equals 56, you would divide 56 by 3. So, 56 divided by 3 equals 18.6666667. Therefore, 18.6666667 times 3 equals 56.
How do you find the answer to this equation: 3n equals 18
y = 3x y = 3*19 = 57
y varies directly as x y=kx, where k is a constant y=18 when x=3 18=3k k=6 y=6x
y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.

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.
f = 54
In order for us to answer the question, you'll need to first take the following steps: -- re-read the question carefully -- compare it with the book you copied it from -- correct the misquotes, errors, typos, and points of confusion -- post the question again
