So you would divide 43.65 by 5 hours (to get 8.73), then you multiply by 7, and your final answer is $61.11
Hope that helps :)
y= -4x and 8x-y=6
what you do is switch the negative y to the other side and move the positive 6 to the other side thus making y=8x-6.
I don't get what those numbers are on the question but the way you solve it is by combining them and putting one y into the other
8x-6=-4x 12x=6 6/12=x .5=x
then you plug in x to find y in whichever equation:
-4x=y -4(.5)=y -2=y
so the final answer would be (.5,-2)
Answer:8

Answer:
The area of the cover for the hot tub must be:
Step-by-step explanation:
First, you must understand that since a hydromassage tub is mentioned and the diameter, it is assimilated that it is round in its upper part, which is why the formula is used to find the area of a circle:
- <u>Area of a circle = pi * radius ^ 2</u> (you must know that the radius is half the diameter)
Since the diameter is mentioned, it can be replaced in the formula:
- Area of a circle = 3.14 * (3.5 feet) ^ 2
- <u>Area of a circle = 38,465 square feet. Approximately 38 square feet</u>.
