Answer:5=13
Step-by-step explanation:
Open parenthesis so you do 4 time 2 and 2 times 2. you get 8-3=4+9. 8-3=5 and 4+9=13. So your final answer is 5=14. I am not sure if you can simplify it further.
Answer:
a) c = 15t
Step-by-step explanation:
c = the total cost of the breakfast tickets
t = the number of breakfast tickets bought
Tickets for an all-you-can-eat pancake breakfast cost $15 each
Therefore, the equation that shows the relationship between c, the total cost of the breakfast tickets and t, the number of breakfast tickets bought is written as:
c = $15 × t
c = 15t
Option a is the correct option
Answer:
10626 different arrangements
Step-by-step explanation:
As we have a total of 23 students and we want to form groups of 3, where the order of the 3 students matters, we can solve this problem using a permutation of 23 choose 3.
The formula for a permutation of n choose p is:
P(n,p) = n! / (n-p)!
So, using n = 23 and p = 3, we have:
P(23,3) = 23! / (23-3)! = 23! / 20! = 23 * 22 * 21 = 10626
So we have a total of 10626 different arrangements of first, second and third place.
