There is only one freshman in the cast of a high school play. there are 6 sophomores and 11 juniors. one third of the cast are seniors? how many seniors?

Let X = total students in musical

Then (1/3) X = number of seniors

  1 + 6 + 11 + (1/3)X = X

              18 + (1/3)X = X

                           18 = (2/3)X

                 (3/2)(18) = X

                          27 = X

27 students in musical of which one third are seniors,  

there are 9 seniors in musical

hope this helped!

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
