X = Y = 9 The answer must be 9, since it says it in the problem. x = 9, y=9, and x = y are all true based on the given info.
the product of -6 and a number, x, decreased by 9, is -33. what is the number?
199 - 9% = 199 x (1 - (9/100)) = 199 x 0.91 = 181.09.
y = x-9 here y is the new number when the original number x is decreased by 9
8-x 8-x
Answer: 45% Work: 20 is decreased to 11 9 = D x 20 --- ---- 20 20 20 divided by 9 = .45 .45 as a percent = 45 %
let x = number x - .125x = 420 .875x =420 x = 480
5(x^2 + y)
9 x 3/2 = 27/2 = 13 and a half
A number y decreased by 1 is equivalent to which of the following expressions? y - 1 y = 1 y + 1
Cut in half, decreased by 50%.
35-2x<18 35<18+2x 35<2(9+x) 17.5<9+x 26.5<x
kVp is the penetrating ability of an x-ray and half value layer is the amount of filtration or thickness of an object needed to reduce the intensity of the x-ray by half. So if you decreased kVp, then the half value layer would decrease.
