Answer:
12 (18+x)
Step-by-step explanation:
X equals 38. That means, angle R is 38, angle P is 69, and angle Q is 73.
You get x=38 by doing x+35+x+2x-7 = 180

Answer:
-14
Step-by-step explanation:
8x-y²-3
8(-1/4) - (3)² - 3
-2 - (9) - 3
= -14
3(2a+1)=-5(a+6)
First expand the brackets.
6a+3=-5a-30
Now add 5a to both sides.
11a+3=-30
Then subtract 3 from both sides.
11a=-33
Finally divide both sides by 11.
a=- 33/11
=-3
-6 x -4 = 24
24/-6 = -4
24/-4 = -6
Hope this helps :)
