12/30 = x%, so 40%.
-40
x + 3x = 40 4x = 40 x = 10.
x/7 = 40 Therefore, x = 7 x 40 x = 280
x equals -12 and y equals 1/4 of -12, so y = -3.
12/30 = x%, so 40%.
-40
(12 / 30) x 100 = 40Therefore, 12 is 30 percent of 40.
x = 40
If 40 plus x equals 25 then x is equal to -15.
To find the integer that, when increased by -12, equals 28, we can set up the equation: ( x + (-12) = 28 ). Simplifying this gives ( x - 12 = 28 ). Adding 12 to both sides, we find ( x = 28 + 12 ), which results in ( x = 40 ). Therefore, the integer is 40.
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
x + 3x = 40 4x = 40 x = 10.
12 / 40 as percentage = (12 * 100) 40 = 30 %
40-n equals 28 = 12
x/7 = 40 Therefore, x = 7 x 40 x = 280
x equals -12 and y equals 1/4 of -12, so y = -3.
