8.61 to the nearest tenth is 8.6
The answer is 8 by itself i think
(X/3) - 8 = 12
X being a number divided by 3. This part in parentheses so you solve it first. Subtract 8 from that and your answer equals 12.
True because yes yes yes yes yes
The GCF of the three terms (9a, -18b and 21c) is 3
Rewrite each of the terms so 3 is a factor
9a = 3*3a
-18b = -3*6b
21c = 3*7c
So we can say...
9a - 18b + 21c = 3*3a - 3*6b + 3*7c
9a - 18b + 21c = 3(3a - 6b + 7c)
Answer: 3(3a - 6b + 7c)
If you distribute outer 3 to each of the inner terms and multiply, you'll get the original expression again.
