Lets x is the labor charges per hour
3x + 126.53 = 220.28
3x = 220.28 - 126.53
3x = 93.75
x = 93.75 / 3
x = 31.25
answer: $31.25 per hour charged for labor
Answer:
Circumference.
Step-by-step explanation:
The distance around a circle is its circumference.
The distance around a circular region is known as its CIRCUMFERENCE.
Let the length equal x
Then the width would be 4x + 8 (8 feet more than 4 times the length)
Area = length x width:
5,472 = x * 4x+ 8
Simplify:
5472 = 4x^2 + 8x
Subtract 5472 from both sides:
4 x^2 + 8x - 5472 = 0
Use the quadratic formula to solve for x.
X = 36
Now you know the length is 36 feet
The width = 4(36) + 8 = 152 feet
Now find the perimeter: 152 + 152 + 36 + 36 = 376 feet.
The answer is B. 376
RU is 34. To find the answer you can use a proportion. In this problem the proportion would be 60/51 = 40/x. You can then cross multiply giving you 51*40=60x. You can then solve for x which is your answer.
