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?
The expression can be simplified by combining like terms.
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)
