You can buy 6 buckets
Step-by-step explanation:
30=-12+3x
-12.  -12
18=3x
divide by 3
you can buy 6 buckets
 
        
                    
             
        
        
        
Answer with Step-by-step explanation:
The given differential equation is 

Now the above differential equation can be re-written as

Checking for exactness we should have



As we see that the 2 values are equal thus we conclude that the given differential equation is exact
The solution of exact differential equation is given by

The value of  can be obtained by differentiating u(x,y) partially with respect to 'y' and equating the result with P(x,y)

I'll give a practice problem to help explain it a bit better. 
Here, let's try to solve 45% of of 60.
First, we convert the percentage into a decimal. To turn any percentage into a decimal you move the point two spaces to the left.
That means 45% as a decimal is .45.
Next, we multiply our number, 60, by the decimal .45.
60×.45=27.
That means 45% of 60 is 27.
To sum it all up, you have to get the percentage, move the decimal point two spaces to the left, and multiply it by the number you were trying to find the percentage of.
Have a wonderful day! :)
