Step-by-step explanation:
Using the Fundamental Counting Theorem, it is found that there are 576 ways for the dancers to line up.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:
![N = n_1 \times n_2 \times \cdots \times n_n](https://tex.z-dn.net/?f=N%20%3D%20n_1%20%5Ctimes%20n_2%20%5Ctimes%20%5Ccdots%20%5Ctimes%20n_n)
In this problem, considering the order:
Black - Red - Black - Red - Black - Red - Black - Red
The number of ways for each is given by:
4 - 4 - 3 - 3 - 2 - 2 - 1 - 2
Hence:
![N = 4^2 \times 3^2 \times 2^2 = 576](https://tex.z-dn.net/?f=N%20%3D%204%5E2%20%5Ctimes%203%5E2%20%5Ctimes%202%5E2%20%3D%20576)
There are 576 ways for the dancers to line up.

Answer:-3/4
Step-by-step explanation:
Get the x by itself by dividing both sides by 8 then reduce -6/8. When you reduce you get -3/4
