Anita can clean 1/8 portion of the pool in 1 hour
Chao can clean 1/6 portion of the pool in 1 hour
Both of them working together can clean 1/8 + 1/6 = 7/24 portion of the pool in 1 hour
Therefore, it will take both of the working together 1/(7/24) = 24/7 or 3 3/7 hours to clean a typical pool.
Answer:
1/2 or 0.5
Step-by-step explanation:
since 7 out of 14 shirts sold were green, the probability would be 7/14. but since you need to simplify, it will be 1/2 or 0.5
6×5=30. the sum of the five numbers is 30. then just do 30-7-8-5-2=8. 8 is the number on the bottom card.
Lines that are parrellell presume to have the same slope.
So if we just calculate the slope of a function or a line we should be good.

Now put in the data from the coordinates of the points 

The form of a function now looks like:
From here we are no longer required to calculate anything more. Leave n alone.
The solutions are the equations of the form above.
That would mean:

Hope this helps.
