Jalesa,   This problem sets up a relationship for you to use.  It is basically saying that 60 feet is to 20 pounds/square inch as 150 feet is to x pounds/square inch.  You could write them as ratios equal to each other:  60 feet:20 pounds/square inch = 150 feet:x pounds/square...

Brit, Is that supposed to be a square root or a v in front of the 110?  Also, I think everyone here is perplexed at why there would be a X and a x.  If a v is before 110 that confuses us also.  Are you given any more information at all?   Michelle

The expression can be simplified by combining like terms. 5m-2m=3m 3k+5k=8k So, the expression would now read:  3m+8k. If there is nothing else specified with this problem you are finished.

Set up the problem as follows: R = the number of hours Ron Worked number of hours Mary worked = (2R +3)  (2R is twice the amount of hours that Ron worked, and add 3 to get 3 more hours, as stated in the problem.) They worked together a total amount of 57 hours, so an equation...

The only other thing you need to know that I did not explain in your multiplication question is the way to divide fractions.  Dividing fractions = multiplying fractions by flipping the numerator and denominator in the second fraction.   So, 18x7 -  divided by  2x7y4   ...

First, simplify the expressions by factoring them out.  For example, a2 + 7a + 6 becomes (a + 6) (a+1).   If you do this, the fraction then looks like this:   (a+6) (a+1)     times     (a +4) (a -2) (a+5)(a-2)...
