Answer= 4 hours.
The first pipe can fill one pool in nine hours. So in one hour, it can fill 1/9th of the pool. Same with the other pipe, it can fill 1/6th of the pool in other hour.
So 1/9 + 1/6 would represent the first hour of filling the pool. Since 1/9 + 1/6 = .277.. , 27% of the pool is filled. Repeat this until you get to 100% (full pool).
First hour, 1/6 + 1/9 = .27
Second hour, 2/6 + 2/9 = .5
Third hour, 3/6 + 3/9 = .83
Fourth hour, 4/6 + 4/9 = 1.11
So in 4 hours, the pool will be filled.
I would easily recommend to convert these to decimals. If you don't know how you should search it up or ask a teacher/friend. Convert 2 3/4 to .75, and then 2 1/2 is 2.50. Add 2.75 twice because he is making 2 dozen each (and a half) equals 11. Then multiply the 2.75 by .50 (6 muffins). That is 1.375. Add 11 and 1.375 equals 12.375. I'm not 100 percent sure this is correct but I hope it helps. :)
Answer:
I think what you wrote is the following: I want to know the binomial of 3(3x-2y)
The answer would be 9x-6y
Step-by-step explanation:
Distribute the 3 into the numbers in parentheses.
Multiply the numbers 3x and -2y by 3
Hope I helped, have a nice day :)
Answer:
One solution.
Step-by-step explanation:
1/2x + 12 = 4x - 1
12 + 1 = 4x - 1/2 x
13 = 7/2 x
x = 13 *2/7 = 26/7.
