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:-
Now, the number of different recital programs are:-
Hence, there are 1,16,280 different recital programs possible.

Yes
To figure out if x = 2 is a solution, plug 2 in for x. If the left side is greater than 10, then x is a valid solution. If the left side is not greater than 10, than x is not a valid solution.
3x+5>10
3(2)+5>10
6+5>10
11>10
11 is actually greater than 10, so x=2 is a solution to this inequality
Answer:
6l + 6r = 108
Step-by-step explanation:
We have that, total number of lilies used = 30 and total number of roses used = 78.
So, the total number of flowers are = 30 + 78 = 108
Let, l = number of lilies in one arrangement and r = number of roses in one arrangement.
Since, it is required to make 6 identical arrangements.
So, number of lilies in 6 arrangements = 6l and number of roses in 6 arrangements = 6r
Thus, we get the relation between lilies and roses as 6l + 6r = 108.
I’m sorry if this is wrong, but wouldn’t it be 30;60? Again if I’m wrong someone else feel free to answer and correct me
