Answer:
14.
Step-by-step explanation:
3x + 7y = 12
x - y = 1 Multiply this by -3:
-3x + 3y = -3 Add this to equation 1:
0 + 10y = 9
so y = 9/10 = 0.9.
x - 0.9 = 1
x = 1.9.
So 5x + 5y = 5*1.9 + 5*0.9
= 14.
45 degrees
a right angle is 90 degrees and there is a line splitting it in half equaly. We have to also divide 90 by 2 then which is 45 so 45 degrees.
