Let me assume that this equation is -2 -8x = 40
It's usually best to move all the purely numerical items to one side first. Let me move the -2. Then, to do this I add 2 to both sides.
-2 - 8x +2 = -8x = 40 + 2 = 42 or -8x = 42
Now, to yield x 'by itself' let me divide both sides by -8.
(-8x)/-8 = x = 42/(-8) = -21/4 or x = -21/4
40% of 28 can be written as (40/100) x 28 or 0.4 x 28. Therefore your answer is 11.2.
The answer depends on the value of x, which is not given.
(28 ÷ 40) x 100 =0.7 x 100 =7028 ÷ (40 x 100) =28 ÷ 4000 =0.007
To find 40 percent of a value, multiply the value by 0.4. In this instance, 0.4 x 58 = $23.20.
0.7 x 40 = 28.
X - (X * .4) Find 40% of the value and subtract that result from the original value.
x=100
To find 40 percent of a number, multiply the number by 0.4. In this instance, 0.4 x 70 = 28. Therefore, 40 percent of 70 is equal to 28.
40% of 28 can be written as (40/100) x 28 or 0.4 x 28. Therefore your answer is 11.2.

To find 40 percent of a value, multiply the value by 0.4. In this instance, 0.4 x 58 = $23.20.
2 x 2 x 7 = 28 2 x 2 x 2 x 5 = 40
0.7 x 40 = 28.
x + (-12) = 28 So x = 28 + 12 = 40
The equation would look like this... x / 40 = 73 / 100 x = (40 x 73) / 100 x = 2800 / 100 x = 28 So 28 is 73% of 100.
If you mean 2x = 28 then the value of x is 14
