Step-by-step explanation:
-8x+5x-9=6
-8x+5x= -3x
-3x=6
6/-3
x=-2
Add 6 to both sides and divide both sides by 5
Answer:
The angle is in the third quadrant.
Step-by-step explanation:
7x= 180-x
7x+x= 180
8x= 180
x= 22.5
the angle is 22.5
its supplementary angle is 157.5
I believe the answer would be 120
Answer:
6 and 2 is the solution
9 and 7 is not the solution
Step-by-step explanation:
6 and 2 is the correct answer as 3*y must equal or smaller than 18, we got:
3y = 3*6 = 18 (Yes)
3y = 3*2 = 6 (yes)
3y = 3*9 = 27 (No)
3y = 3*7 = 21 (No)
Hope this helped :3
