xy = is a constant (k) so k = -360. When y = - 36, x = 10

find x+x+x when x=15 15+15+15=45
The x-intercept is (15 0)
you wanna find out 15n=1275 you have to find out what times what equals 1275 alright =) by a fifth grader Majd Merai =) i rock hehehe

y = 8
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.
15 times 10 equals 150, so to find the remaining 6, divide 6 by 15 which equals 0.4. Therefore, 15 multiplied by 10.4 equals 156.
y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.
If P varies jointly as q, r and s - assume this is in direct proportion, then P ∝ qrs so P = kqrs where k is a constant.70 = k x 7 x 5 x 4 = 140k : k = 140/70 = 0.5When q = 2, r = 15 and s = 7 then,P = 0.5 x 2 x 15 x 7 = 105

To find the number that, when multiplied by 10, equals 150, you would divide 150 by 10. This calculation would give you the number 15. Therefore, 15 times 10 equals 150.
The question is incomplete and unanswerable as written
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.
