We need to find m first.
m+n=12, n=5 (plug in n as 5)
m+5=12 (subtract both sides by 5)
m=7
m-n: we know that m is 7 and n is 5
7-5=2
The final answer is 2.
Answer:
2
Step-by-step explanation:
If <em>m+n = 12</em> and we know what <em>n</em> is, then we can substitute n in to solve for m!
It would look like this:
m + 5 = 12
m = 12 - 5
m = 7
Next, we plug our numbers in for each variable in the next equation <em>(m-n)</em>:
7 - 5
=
<em>2</em>

5y^2 +7
0.76
-8+3=-6x^(2/3)
-5=-6 x^(2/3)
-5/-6=x^(2/3)
(2/3)√{5/6}=x
0.76=x
x=0.76
