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)
Answer:
A
Step-by-step explanation:
Answer:
18
Step-by-step explanation:
The diagonals of a parallelogram <em>bisect</em> each other, which is to say they split each other in half, and since each half length is equal to the other, we can say that
3x + 3 = 6x - 57
Which, after some algebraic manipulation, gives us the solution
x = 18.
Y = k / x
2 = k / 4
k = 8
Therefore, the answer for this question would be (4,2)
Answer:
Step-by-step explanation:
y - 8 = -2/3(x + 3)
the solution is the 4th option
