A=1/10, b=1/12, c=1/15 (these are the rates for each worker...)
1.)
2(1/10)+4(1/12)+t/15=1
1/5+1/3+t/15=1
(3+5+t)/15=1
3+5+t=15
8+t=15
t=7
So it would take c 7 hours to finish the job.
2.)
1/40-1/60
(3-2)/120
1/120
The drain rate is 1/60. So you will need to find t when the tank is empty, while starting at 2/3 capacity...
2/3-t/60=0
(40-t)/60=0
40-t=0
t=40
It would take 40 minutes to empty the tank when it is 2/3 full.

Dunno wat that means im in elementary lel =]
But I know wat its like to not have an answer on a hard question =(
There is not an answer to an expression.
-3+p is an expression, unless there was an equal sign and a sum at the end, that is when we can solve for the variable x.
-3+p simply equals -3+p
Hey there!
The correct choice is D. 5(2 + y)
As you can see, the expression matches the description
5 times = 5( The parentheses directly next to the 5 means to multiply what is inside the parentheses by that number, in this case, 5
The sum of 2 and y = (2 + y)
Therefore, that makes D the CORRECT option
Hope this helps you!
God bless ❤️
