Answer:
4
Step-by-step explanation:
12/2=6
20/2=10
10-6=4
Answer:
Step-by-step explanation:
First let's multiply the 1st equation by 10.
So, we can see that the equations have the same coefficients and that implies they are equal.
So the equation has no solutions for. 
Answer:
A= 37 degrees
C= 43 degrees
Step-by-step explanation:
Hey there!
So this question looks a lot more complicated than it really is.
Complementary angles are the same.
Supplementary angles add up to 180 degrees or in other words a straight line.
If A and B are complementary and B equals 37 degrees, than A is also 37 degrees.
To find C, all we would do is subtract 37 from 180 to find the leftover amount.
180-37=43
So, in conclusion:
A= 37 degrees
C= 43 degrees
Hoped this helped! :D
