Answer:
12 cleaners
Step-by-step explanation:
8 cleaner can clean in 3 hours = 1 office
1 cleaner can clean in 3 hours = 
part of job
1 cleaner can clean in 1 hours = 
part of job
Let the number of cleaner required to finish the job in 2 hours = x
hence
x cleaner can clean in 1 hours = 
part of job
x cleaner can clean in 2 hours = 
part of job
Hence
Hence we need 12 men to complete the same job in 2 hours
Answer:
x = 9
Step-by-step explanation:
When doing these types of problems, the main goal is to get the variable by itself. Its kind of hard to explain with words so I will just use numbers.
15x + 14 = 149
(Subtract 14 on both sides. Remember, when you do something (Like subtracting, adding, etc.) on one side you have to do it to the other.)
15x + 14 = 149
-14 = -14
---------------------------
15x = 135
(Divide 15 on both sides. Since we need to use inverse operation to cancel the 15 out, we would divide 15 on both sides.)
15x/15 = 135/15
x = 9
Hope this helps :)
Answer:
You could cut the shape into 2 different shapes: a triangle and a rectangle, and solve for their areas, then add the areas together.
Step-by-step explanation:
It is bigger than 50, so 25 is out. It is smaller than 105, so 105 and 130 are out. That leaves 75. Process of elimination. I hope this helps.
