In 1 there are 3 thirds so in 9 there will be 3x9 thirds which is 27 thirds.

First we need to find two numbers that multiply to make ac and add to make b which are -6 and 5 in this case.The two numbers that do this are 6 and -1. Now we separate the 5x into 6x and -x. Putting this ...

t Using the fact that d/dx ( ln g(x)) = g'(x)/g(x), we can see that the integral of this function will be an ln function. From observing f(x) we see that if the answer was ln(4x-1) then f(x) would need to...

Let m be the number of males. Let f be the number of females.
(1/3)m + (1/4)f = 66      (1)
m = 2f                   (2)
(1/3) * 2f + (1/...
