We know that the won 3/4. So that means that the remaining 1/4 is the games lost, which is 21.
To find the total games played, we simply multiply 21 by 4 to get 4/4, or the total games.
Answer:
x= 10/3
Step-by-step explanation:
1/250 : 2 = 1/150 : x
it's a simple problem of ratio and proportion
1/250 : 2 = 1/150 : x
⇒![\frac{x}{250}= \frac{2}{150}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B250%7D%3D%20%5Cfrac%7B2%7D%7B150%7D)
⇒![x= \frac{2\times250}{150}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B2%5Ctimes250%7D%7B150%7D)
x= 10/3
Answer: 720 ways
Step-by-step explanation:
We know that the total number of ways to arrange n things in a row in order is given by Permutations.
i.e. The total number of ways to arrange n things in a row= n!
Therefore, the number of ways to arrange 6 unique CD's in order along a shelf will be :
![6!=6\times5\times4\times3\times2\times1=720](https://tex.z-dn.net/?f=6%21%3D6%5Ctimes5%5Ctimes4%5Ctimes3%5Ctimes2%5Ctimes1%3D720)
Hence, there are 720 ways to arrange 6 unique CD's in order along a shelf.
Isolate ry. To do this, subtract s from both sides, obtaining ry = tx - m - s.
Next, divide both sides by r, obtaining y = (tx - m - s) / r.
