Answer:
n = -14
Step-by-step explanation:
-3(n+9)=15
Distribute -3 to (n+9):
-3n - 27 = 15
Add 27 to both sides:
-3n = 42
Divide both sides by -3:
n = -14
To solve this do:
838.35/9315= 0.09.
This means the company charged $.09 for every kilowatt of electricity used.
A= 4.4 B= 0.875 should be the answers
Answer:
49 1/6 meters
Step-by-step explanation:
P = 2(73/3) + 2(61/4)
= 146/3 + 61/2
= 48 2/3 + 30 1/2
= 48 4/6 + 30 3/6
= 48 + 7/6
= 48 + 1 1/6
= 49 1/6
