Answer:
30
Step-by-step explanation:
Given: There are six finalists and two medals. That is it asks for the possibilities of 6 finalists taking two at a time. Say, for example the first and third finalist or the second and the sixth finalist and so on. The number of possibilities is given by 

So the number of possibilities of 6 finalists taken two at a time is 
![$ \implies \frac{6!}{(6 - 2)!} = \frac{6!}{4!} \hspace{15mm} [n! = n \times (n-1) \times (n - 2) \times . . . 2 \times 1] $](https://tex.z-dn.net/?f=%24%20%5Cimplies%20%5Cfrac%7B6%21%7D%7B%286%20-%202%29%21%7D%20%3D%20%5Cfrac%7B6%21%7D%7B4%21%7D%20%20%5Chspace%7B15mm%7D%20%5Bn%21%20%3D%20n%20%5Ctimes%20%28n-1%29%20%5Ctimes%20%28n%20-%202%29%20%5Ctimes%20.%20.%20.%202%20%5Ctimes%201%5D%20%24)

First you do,
3 x 2 =1/4
plus 3 x 2 1/2= ?
Then you will get your answer! Hope it helps!
You can solve a system of equations 3 ways.
1. Elimination
This method is eliminates one of the variables in the system of equations to get 1 equation with only one 1 variable.
2. Graph
You graph both of the equations and find where they intersect if at all.
3. Substitution
If you know the value of one of variables, you can substitute it back into the equation.
False, the side across from the right angle is called the hypotenuse
