Perimeter of rec. = 2 ( l + w )
Given: perimeter of rectangle = 322m, length = 86m
Required: width = ?
Solution: 322 = 2 ( 86 + w )
Divide 322 by 2 ie, 322/2 = 86 + w
Will be equal to 161 = 86 + w
Therefore Width= 161 - 86 = 75
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.
First, lets set up the equation.
0.25x + (1/8)x + 24 = 60
The variable x will be equal to the total amount of the paycheck. We used 0.25 of the paycheck on the first item bought, 1/8 on the second item bought, and then 24 more dollars. After assembling the equation, we merely need to solve for x to find the value of the paycheck. I'll be converting 1/8 to 0.125 at this point for simplisity's sake.
Subtract 24 from both sides.
0.25x + 0.125x = 36
Combine like terms on the left side.
0.375x = 36
Divide both sides by 0.375.
x = 96
The total is A, 96 dollars.
