No
Step-by-step explanation:
Answer:
x = 15
Explanation:
First, add both equations on one side, and set it equal to 180° because it's supplementary:
2x + 8 + 8x + 22 = 180
combine like terms:
10x + 30 = 180
subtract 30 on both sides of the equation and you end up with:
10x = 150
divide both sides by 10 and you get:
x = 15
Answer:
Look below
Step-by-step explanation:
A.
8 + 9 + 10 = 27
9 + 10 + 11 = 30
10 + 11 + 12 = 33
B. Every answer is divisible by 3, every consecutive answer is also 3 more than the one before it.
C. Yes
19 + 20 + 21 = 60
D. No
8 is not divisible by 3. Also, the closest you can get is 6 (1 + 2 + 3) or 9 (2 + 3 + 4).
