I believe the answer is 2/3n
The total cost is 13.76, she has enough money. (accidentally posted the answer in the comments so ignore that)
D. Use the formula V=πr^2 h.
You need to distribute the 4, so you'll end up with:
4n-16=-12
Then, add 16 to both sides.
4n-16+16=-12+16
4n=4
Divide by 4 on both sides.
4/4n=4/4
n=1
Answer:
-n + 2 m + 2
Step-by-step explanation:
Simplify the following:
(-2 n + 4 m + 4)/2
Factor 2 out of -2 n + 4 m + 4:
(2 (-n + 2 m + 2))/2
(2 (-n + 2 m + 2))/2 = 2/2×(-n + 2 m + 2) = -n + 2 m + 2:
Answer: -n + 2 m + 2
