78 i think bc its the only possible way fo get 10 to equal 88 when adding
well, im assuming its talking about a triangle. The total number of degrees is 180. I guess you subtract that by 81. You get 99. But there are still the others. Srry this is how far i can help. But you then go with 99 and divide or sum thing.
Answer:
x = -4 and -2x - 8
Step-by-step explanation:
<u>Step 1: Distribute</u>
-1/3(6x + 15) - 3
-6/3x - 15/3 - 3
-2x - 5 - 3
-2x - 8
<u>Step 2: IF NEEDED SOLVE FOR X</u>
-2x - 8 + 8 = 0 + 8
-2x / -2 = 8 / -2
x = -4
Answer: x = -4 and -2x - 8
Answer:
Step-by-step explanation:
3x-11+6x-10+x=180
10x-21=180
10x=201
x=20,1
