You can find the answer by first dividing 12 by 6 which = 2
so multiply 36 by 2 which =72
72 is your answer ;) hope this helps
Y=1 and x=7 because if you make the first equation into a x= equation, you can just substitute it for the second equation and solve it.
Using the combination formula, it is found that there are 84 ways to choose the three tiles.
The order in which the tiles are chosen is not important, hence the <em>combination formula</em> is used to solve this question.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:

In this problem, three tiles are chosen from a set of nine, hence:

There are 84 ways to choose the three tiles.

1. is the second choice
2. is the first choice
3. is also the first choice
4. is also the first choice
5. is the last choice
6. is the second choice
7. is the first choice
8. is the last choice
9. is the second choice
10. is the last choice
your welcome brainless answer please.
9. Is 37 since you take PR+QR
10. Is 7 since it's PR-QR
11. Is 6 since you take PR-PQ
