I assume you're looking for n.
so, take 2n/10-3n/10=2/10. Making everything have the same denominator is always easier.
This way, you have -n/10=2/10.
n=-2.
In a way, you are adding like terms.
3.5 + 2.7 = 6.2, therefore making the answer 6.2 + x
The brackets can be ignored so you are really just asked 8 x 4 x k. 8 x 4 =32 so you end up with 32k
4 feet? 20/5=4? Not too sure
