Answer:
560
Step-by-step explanation:
The number of ways to choose r objects from n total objects is given by the combination formula:
Where n is the total and r is how many we are choosing
Also note: n! = n * (n-1) * (n-2) * ...
So n = 16 and r = 3, so we have:
hence, there would be 560 different groups of 3

So first you would combine the like-terms so you get:
and combine the second like-terms:
now you only have a two step equation and you continue by doing the reciprocal and you add the -1/5 to the 24.8 where you get:
7/9x=24.6
then because the 7/9 is being multiplied by the x and your trying to isolate it you divide it by the 7/9 on both sides and you'll end up getting
x=31.628571429....
