What is the least common denominator of the fraction 3 x over x plus 1 plus the fraction x plus 1 over 2 x plus the fraction 5 o
Hoochie [10]
3x/(x+1) + (x+1)/(2x) + (5/x)

To find the least common denominator, we multiply the denominators that cannot factor into eachother. x, the denominator in 5/x, fits into 2x, so we do not need to multiply this number.
Therefore, the least common denominator is:
2x(x+1) 

The first term will be multiplied by 2x/2x
The second term will be multiplied by (x+1)/(x+1)
The third term will be multiplied by 2(x+1)

You rise 15 feet for every 1000 feet you drive forward, what is the slope?
liberstina [14]
The slope is:  \frac{3}{200} .
________________________________________________________
Note:
________________________________________________________
slope = rise/ run = 15 ft/ 1000 ft ;

          = 15/1000 = (15÷15) / (1000÷15) ;

            =  1/ (200/3) = 1* (3/200) = [tex] \frac{3}{200} [/tex] .
