1. Isolate the variable
Ex. 3n=12 Divide 3 on both sides. You get n=4
2. Inequality
Ex. 3x>x+7
3. Distributive Property
-10(x+5)=40
-10x-50=40
To do this problem, we must first distribute the 13 and 14 into the parenthesis.
<span>13(9−6m)+14(12m−8)
117 - 78m + 168m - 112
To combine like terms, we can add/subtract terms that have an "m" together and then we can add/subtract terms that do not have "m" together.
117 - 112 = 5
and
168m - 78m = 90m
So our final sum is 5 + 90m</span>
Answer:
Im 95% sure that it is most likely the first one.
Step-by-step explanation:
you can estimate 17/18 - 3/7 = 65/126 to estimate the answer to 70/130. i think that's what you are asking
