Okay so in school I am doing this litterly right now. So all u have to do is when it is a different sign you subtract, when it is the same you add. So think of it as, Different/Difference and Same/Sum. when the sign is different u find the difference and when u have the same sign you find the sum.
Example 1: -3+8= 5
Use the same sign as the largest number
Example 2: 5+(-10)= -5
Hopefully This helped! It is easier then you may think once you get the hang of it! ( You get the hang of it REALLY fast ) :)
It is 23a+72
see
6(-3a+12)+8a-13a
-18a+72+8a-13a
23a+72
do you understand
Rime: A number with exactly two factors; one and itself. What does this mean? This means that for us to call a number prime, only two whole numbers can divide into it without a remainder. Here are a few examples: 2, 3, 5, 7, 11<span>, </span>13<span>, </span>17<span>, </span>19<span>, </span>23<span>, and so on.</span>
In this problem WP means what percent
20 = WP X 160
solve for WP, by dividing both sides by 160
and you get:
0.125 = WP
Change your decimal into a percent by multiplying by 100%
12.5% is your result.
