8 = .40(x)
8(10/4) = .40x(10/4)
80/4 = x
20 = x
x is 20, but you REALLY should start doing your homework and paying attention in class. Learning is important.

∙ 14y agothe percent of a number is when you multiply the percentage by the number, for example: 8% of 40 40 x 0.08= 20% or 20% of 40 0.20 x 40=8%
Saying that 24 is 60% of x is the same as saying: 24 = 60/100 ⋅ x So simply solve for x: ∴ 24 = 3x / 5 ∴ 8 = x / 5 ∴ x = 40
Is it 15 over 40?
40 x .20 = 8 So 8 is your answer.
75 percent is equal to 0.75, so the expression would look like (0.75x) +8. But if you do not know what it equals to it is not an equation and you can not solve it.
8/40 x 100 = 20 percent.

8 divided by 10 gives 10%, which is 0.8. This is simply multiplied by 4 to find 40%, which is 3.2

5 x 8 = 40
% rate:= (20/8) x 100%= 2.5 x 100%= 250%
You solve the equation by manipulating it until you have only "x" on one side.12/8 = (x/40) - xSo we can multiply both sides by 40 to get rid of the x/40:12/8 * 40 = x - 40x60 = -39xx = 60/-39x = -1.538 (to 3 decimal places only)IF you actually meant (and this is why it is important to write our questions as accurately as possible else mathematicians will assume you are using the agreed conventions):12/8 = x/(40 - x) thenx = 12/8 * (40 - x)x = 60 - 1.5x2.5x = 60x = 24
75 percent is equal to 0.75, so the expression would look like (0.75x) +8. But if you do not know what it equals to it is not an equation and you can not solve it.
First, 10% = 8 so 10% x 4 = 40% which is 8 x 4=40% 8 x 4 = 32. So now u know that 40% of 80 is 32.
The answer is 40 on a scientific calculator 32/4 = 8 4 x 8 = 32 8 + 32 = 40.
