2x+18=30
-18. -18
2x = 12/2
x=6
Answer: Supplementary angles have a sum of 180 degrees so you would subtract 79 from 180 to determine the value of its supplement which would be 101 degrees
While complementary angles have a sum of 80 degrees. So you would subtract 59 from 80 and that leaves you with 21, so the complement angle is equal to 21 degrees
Step-by-step explanation:
Answer:
first is 4^2 (add powers)
Second is a^(m-n) (subtract powers)
Answer:
x = 8
Step-by-step explanation:
- Write it out:
- Add 5 to each side, so it now looks like this: 3/2x = 12
- Divide each side by 3/2 to cancel out the 3/2 next to x. It should now look like this: x = 8
I hope this helps!
