-7 is the answer to your question
8 - 3x + 12 = 2x
(Distribute the -3 to the quantity in the parentheses)
20 = 5x
(Simplify by adding like terms)
4 = x
(Divide both side by 5 to isolate the variable)
X = 4
Answer:
6720 ways different
Step-by-step explanation:
In this case, we must calculate the different ways using the permutation formula:
nPr = n! / (n - r)!
where n is the total number of people and r would come being the group of person that you want to put together the groups, therefore n = 8 and r = 5
replacing:
8P5 = 8! / (8 - 5)!
8P5 = 6720
That is to say that there are 6720 ways different winning groups are possible
4 is the median! Because the middle numbers are 8 and 4 and if you add them you get 12 and 12 divided by 2 equals 4
