163-x=-52
first subtract 163 and you get -215
now it looks like -x=-215
then the negative signs cancel out and its now x=215
Answer:
Controlled Observation
Step-by-step explanation:
Answer..
In each arrangement, there are 10 flowers. The daisies are 2/10. multiplying 2/10 to 10, we get 2. So there are 2 daisies.
If Morita makes 4 arrangements, then the number of daisies she needs is
= 4 * 2
= 8
So she need 8 daises for here 4 arrangements.
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.
