Answer:
solve 7+x-15=-2 2/3
Step-by-step explanation:
7+x-15=-2 2/3 -8+x=-8/3 x=-8/3+8 x=16/3 first question answer second question answer 5 1/3 5*3+1/3 15+1/3 16/3 3rd questiin answer 10 2/3 10*3+2/3 30+2/3 32/3 solve by this method another question
9m+6m^2n
12mn-3mn=9mn
4m^2n+2m^2n=6m^2n
==> 9m+6m^2n
or rewrite as 3m(3+2mn)
20
4 + 2 + 5 + 4 + 0 + 1 + 1 + 3 = 20
