Answer:
x = 40
Step-by-step explanation:
Step 1: Write out an equation
4/5(x) = 32
Step 2: Solve by dividing both sides by 4/5
x = 32/(4/5)
<em>Use KCF (Keep Change Flip) if you do not have a calc.</em>
x = 40
Answer:
x is 2.88 which can be rounded up to 2.9
Step-by-step explanation:
Subtract 2/3x from 5x.
Add 1/2 to 12.
Simplify and put into calculator (y=) to double check.
X=time of the third person it would take to fill the pool
We can suggest this equation:
6[(1/20) + (1/15) +(1/x)]=1
6[(3x+4x+60)/60x]=1
(7x+60)/10x=1
7x+60=10x
7x-10x=-60
-3x=-60
x=-60/-3
x=20
Answer: the third person alone would fill the pool in 20 hours .
Answer:
-3/5
Step-by-step explanation: I got -6/10 but you can simplify that sooo
Answer:
hours is closest to 2 hours.
Step-by-step explanation:
We have been given three numbers and we need to decide which of the three numbers is closest to 2.
In order to decide that, we will convert each of the given numbers into decimals and then we will compare.
Upon comparing 2.750, 2.375 and 2.600 we know that 2.375 is closest to 2. Therefore, out of the given three numbers, is closest to 2.
