An octopus has 8 tentacles
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:
A, B, and B.
Step-by-step explanation:
-2
-5
Right on the number line, -2 > -5
Answer:
first deal with g(-1)
y=4a - 3
a=4y -3 and now make y the subject again
a+3/4...now put it into f(a)
2(a +3/4) simplyifying
a+3/2 as yo final ans
