You have to calculate how many ways you can select six things (r)
from a set of 9 things (n). (See attached formula).
9! / 6! * (3!) =
9*8*7 * 6! / 6! * 3! =
9*8*7 / 3! =
3 * 4 * 7 = 84 lineups
Answer:
11
Step-by-step explanation:
The equation 44 - x + 2x = 50 can be used to determine the number of cats/kittens adopted.
Step-by-step explanation:
Given,
Number of cats/kittens at the event = 44
Number of cats/kittens at the end of event = 50
Let,
x be the number of cats/kittens adopted
Therefore;
Number of cats/kittens returned = 2x
Number of cats/kittens at the event - adopted + returned = Number at the end of event
44 - x + 2x = 50
The equation 44 - x + 2x = 50 can be used to determine the number of cats/kittens adopted.
