In year 7 of a large comprehensive school is it possible to divide the pupils into equal sized classes of either 24 or 30 or 32 and have no pupils leftover. find the size of the smallest entry that makes this possible. how many classes will there be if each class was to have 24 pupils.

Last part 24x

Step-by-step explanation:

I understand some of this, like the last question. if each class had 24 pupil, and were trying to find out how many are in each class, it would be 24x (x stands for the amount of classes)

You have not given a true amount of pupils so I can not give a 100% correct answer for the first part.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
