Answer:
1330 rounds of meetings
Step-by-step explanation:
You have a total of 21 people, and they all want to meet with each other in groups of 3. This means we are dealing with a combination problem, where combination is the selection of items in which order does <em>not</em> matter.
Formula for combination:
ₙCᵣ =
where <em>n</em> is the total number of objects (in this case, total number of people: 21), and r is the sample set (in this case, groups: 3).
We plug in and get:
->
-> 1330 different meetings for everyone to meet with each other in groups of 3.
Answer:
There are 4 prime numbers from 1 to 10: 2, 3, 5, and 7. This means that there are 4 ways to choose the first outcome. There are 5 composite numbers from 1 to 10: 4, 6, 8, 9, and 10 (1 is just 1). So, you just multiply the two numbers together because each depends on each: 4 * 5 = 20 outcomes.

<em><u>Explanation</u></em>
The given equation is:
First we will <u>simplify the left side by distributing 2</u>. So.......
Now <u>adding 8 to both sides and subtracting 5x from both sides</u>, we will get......
So, the solution is:
Charlie's solution is incorrect as he made a <u>mistake while distributing 2 on the right side</u>. The correct steps will be..........
The solution of Charlie's equation will be:
