3.18 is the answer i believe !
Twelve men take 6 hours to finish a piece of work.
In 1 hour, the 12 men will finish 1/6 of the work
( 1 job ) / ( 6 hrs ) = ( 1/6 of a job ) / ( 1 hr )
-----------------------------------------
That means there is of the job
left to do.
-------------------
If 12 men take 6 hours to finish a piece of work,
1 man will take 12 times as long, to finish the work, so
( 1 job ) / ( 6*12 = 72 hrs ) = rate of working for 1 man, or
-------------------
After 1 hour, there are a total of men working
20 men will work 20 times as fast as 1 man on the
of a job that remains, so
Let = hours for the 20 men to finish the job
To convert an equation to slope intercept form, you have to isolate the y variable.
-2x + 3y = 15
Add 2x to both sides.
3y = 2x + 15
Divide all terms by 3.
<h3>y = 1.5x + 5 is the original equation in slope-intercept form.</h3>
I hope this answers your question!
The answer to -15.375÷0 would be neither. This is because you can't divide any number by zero. Any number tried to be divided by zero would be undefined.
R:{-46, 52}. You cannot repeat any numbers and the order is from least to greatest.
