The answer to this would be 40 because you multiply 12x0.30 and get 40 which mean 12 is 30% of 40 total
Answer:

Step-by-step explanation:
we know that
A linear pair is two angles that are adjacent and form a line. The angle measure of a line is 180 degrees
In this problem we have that
--- by supplementary angles (form a linear pair)
solve for x




Since we are evaluating, we use PEMDAS so we know the order the operations. Follow PEMDAS:
Original Expression: (-1)8+(-1)7-16-14-(-1)2.
Evaluating: -8-7-16-14+2
-8-7=-15-16=-31-14=-45+2=-43.
The answer is -43 according to PEMDAS.
