Answer:
120º
Step-by-step explanation:
All of the interior angles of a triangle have to add up to 180º, so the missing interior angle is 60 degrees once you add 24 and 96 and subtract the sum of 120 from 180.
As for the missing angle, it's supplementary with the interior one that was originally unknown. Subtract 60 from 180, and that will give you 120º.
2800 + 3200 + 3600 = 9600kWh
9600kWh divided by three is the average energy usage per month
3200kWh
3200kWh times by 3 cents is the average cost per month in cents
9600 cents
divided by 100 is the price in dollars

Answer:
s = -3
Step-by-step explanation:
8s + 9 = 7s + 6
Subtract 7s from each side
8s-7s + 9 = 7s-7s + 6
s+9 = 6
Subtract 9 from each side
s + 9-9 = 6-9
s = -3
