Josh can paint a whole room in m hours while Kevin can paint a whole room in n hours. How many parts of the room can they paint
Leona [35]
<h3>Answer: (m+n)/(mn)</h3>

Work Shown:

Josh:

1 room = m hours

1/m room = 1 hour

Kevin:

1 room = n hours

1/n room = 1 hour

We see that the rates for Josh and Kevin are 1/m and 1/n respectively. This is the amount of a room they paint in one hour. Combine the fractions

1/m + 1/n = n/(mn) + m/(mn) = (n+m)/(mn) = (m+n)/(mn)

The expression (m+n)/(mn) represents how much of the room they get painted in 1 hour. This is if they work together and it assumes neither worker slows the other one down.

What is the value of x<br> 2x+3y=45 <br> x+y=10
Volgvan
Assuming this is a system of equations, here is how to find x. 

2x + 3y = 45
x + y = 10 

Multiply x + y = 10 by 2 so you are able to use the elimination method.

2x + 3y = 45
2x + 2y = 20

Subtract.

y = 25

Now that we've found y, we can plug it in to find x. 

x + 25 = 10

Subtract 25 from both sides.

x = -15
