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

Answer:
The costs will be the same at 21 pounds.
Step-by-step explanation:
Let p be the number of additional pounds. (Total weight would be p+1).
UPS cost = 7 + 0.20p
FedEx cost = 5 + 0.30p
We need these to be equal.
7 + 0.20p = 5 + 0.30p
0.10p = 2
p = 20
Hello!
So the problem is 2x-8 = 2(x-4). First off, let's perform the distributive property on the right side of the expression. 2 * x is 2x. 2 * -4 is -8. That makes the right side 2x-8. 2x - 8 = 2x-8, so nothing else needs to be done. Because both sides are identical, all real numbers are the solution.
