-12 + 20 = 8
then divide the answer by -4
8/(-4) = -2
when you divide a negative number, the answer will be the opposite sign of the numerator
-2 is your answer
hope this helps
Answer:
x=8
RPS = 36
Step-by-step explanation:
QPS = 180
The two angles that form QPS
QPR + RPS = 180
7x+88 + 3x+12 = 180
Combine like terms
10x+100 =180
Subtract 100 from each side
10x = 180-100
10x = 80
Divide by 10
x =80/10
x = 8
RPS = 3x+12
= 3(8)+12
24+12
36
40/50=0.8
0.8*100=80%
Hope this helps!
