Total number of ways to make a pair:
The first player can be any one of 7 . For each of those . . .
The opponent can be any one of the remaining 6 .
Total ways to make a pair = 7 x 6 = 42 ways .
BUT ... every pair can be made in two ways ... A vs B or B vs A .
So 42 'ways' make only (42/2) = 21 different pairs.
If every pair plays 2 matches, then (21 x 2) = <em><u>42 total matches</u></em> will be played.
Now, is that an elegant solution or what !
Answer: (-2,1)
Step-by-step explanation:
Read it lije (x,y)
The answer to your question is b
So basically the x will want to be singled out and 3/2-y=the variable
Younger than = less than
Less than symbol = <
People cannot have a negative age, so a must be positive
B. <span>a < 18 and a must be a positive number</span>
