Answer:
Step-by-step explanation:
add 14.52 to both sides of the inequality to cancel that value out from the middle. Then you can divide both sides by 3x to get x by itself in the middle.
There are 1,16,280 different recital programs possible.
Given: A pianist plans to play 4 pieces at a recital from her repertoire of 20 pieces and is carefully considering which song to play first, second, etc.
It means the repetition of pieces is not allowed.
When repetition is not allowed, then the number of ways to arrange n things where r things taken together is given by:-
![^{n} P_{r} =\frac{n!}{(n-r)!}](https://tex.z-dn.net/?f=%5E%7Bn%7D%20P_%7Br%7D%20%3D%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D)
Now, the number of different recital programs are:-
![^{20} P_{4} =\frac{20!}{(20-4)!}=\frac{20*19*18*17*16!}{16!}=116280](https://tex.z-dn.net/?f=%5E%7B20%7D%20P_%7B4%7D%20%3D%5Cfrac%7B20%21%7D%7B%2820-4%29%21%7D%3D%5Cfrac%7B20%2A19%2A18%2A17%2A16%21%7D%7B16%21%7D%3D116280)
Hence, there are 1,16,280 different recital programs possible.
