-117
Answer:
The angles are adjacent. x=20
Step-by-step explanation:
The angles should add up to 180 because they are supplementary.
7x+x+20=180
8x+20=180
180-20=160
8x=160
x=20
Answer:
-13p - 12
Step-by-step explanation:
2(-4p-6)-5p
Distibute 2:
-8p - 12 - 5p
Combine like terms:
-13p -12
Step-by-step explanation:
I cant show a number line so i'll do my best to explain how its graphed.
15) x - 1 < 15
add 1 to both sides:
x < 16
Because it is less than, rather than less than or equal to, it's graphed with an open circle (not filled in) on 16, and everything less than 16 highlighted
---------------------------------------------------------
16) 2(y + 1) - 2 ≥ 12
distribute the 2:
2y + 2 - 2 ≥ 12
combine like terms
2y ≥ 12
isolate y:
y ≥ 6
This one is greater than or equal to, so it's graphed with a closed circle (filled in) and everything above 6 highlighted
