Answer:
Kenjii can use 13.19 kilowatt-hour.
Step-by-step explanation:
Giving the following information:
Kenji's electricity bill costs $21.56 per month plus $2.46 per kilowatt-hour.
<u>First, we will structure the total cost formula:</u>
Total cost= 21.56 + 2.46*x
x= kilowatt-hour
54= 21.56 + 2.46x
32.44= 2.46x
13.19= x
Kenjii can use 13.19 kilowatt-hour.
Since (x+90) and 4x are vertical angles, and vertical angles are congruent, you can set them equal to each other.
x+90=4x
90=3x
x=30
The answer is choice D:
exponents are listed from highest to lowest.
