Answer:
You need the combinations formula:
Combinations = n! / (r! * (n-r)!)
where n = total # of choices (8) and r = # of choices (4)
Combinations = 8 * 7 * 6 * 5 * 4! / (4! * 4 * 3 * 2 * 1)
Combinations = 8 * 7 * 6 * 5 / 4 * 3 * 2 * 1
Combinations = 7 * 2 * 5
Combinations = 70
Step-by-step explanation:
p = 3r + 2s
p - 3r = 2s <em>subtract 3r from both sides</em>
(p - 3r)/2 = s <em>divide both sides by 2</em>
Answer: (p - 3r)/2
$7.5 * 10^9 = $7.5 * 1,000,000,000 = $7,500,000,000
It is seven billion, five-hundred million dollars.
Answer:
O 5
Step-by-step explanation:
Sorry if I am wrong .
But please see
P = 2w + 2L
Flip
2w + 2L = P
Subtract both sides by 2L
2w = P - 2L
Divide both sides by 2
w = (P - 2L) / 2
You chose the right answer choice!
Have an awesome day! :)
