The goal is to get x by itself. All we need to do is work around it.

1. -5x + 2 = 67
2. The reversed operation, or the opposite operation, for addition is subtraction. Thus subtract 2 from 67 and 2. The 2 should cancel itself out. -5x + [2-2=0] = 67 - 2 = 65 -> -5x = 65.
3. The reversed operation, or the opposite operation of multiplication is division. Thus divide 65 and-5 as well as -5 and -5. [-5/-5x = 1x. 1x -> 1 * x = x.] = 65/-5 = -13 -> x = -13.
4. Check your answer by plugging in -13 where x is. Solve with pemdas.

-5(13) + 2 = 67 -> 65 + 2 = 67 -> 67 = 67. Therefore the answer is -13.

(a) <br> 127.5<br> is what percent of <br> 51<br> ?

ExtremeBDS [4]

To solve this, you need to divide 127.5 by 51:
127.5/51 = 2.5
To find the percent, multiply 2.5 by 100:
2.5 x 100% = 250%
So 127.5 is 250% of 51

Here is a uniform probability distribution.

Darya [45]

a) $P(4\le X\le6)=\dfrac25$ because it is equal to the area of the shaded region between X=4 and X=6, and the probability that X falls within some interval is given by the area under the PDF.

b) $a=3$ because the shaded region is a rectangle of height 1/5 (by virtue of X following a uniform distribution over the interval [2, 7], which has length 5).
