Answer:
455.
Step-by-step explanation:
Yes. You require the number of combinations of 3 from 15.
15C3
The formula for this is 15! / 12! 3! or you can do itr as follows
15C3 = 15*14*13/3*2*1
= 5*7*13
= 35*13
= 455.
So from 80 to 64, the change is the difference or 16 books.
now, if we take 80 to be the 100%, how much is 16 off of it in percentage?
Word form-five hundred six thousand,seven hundred nine
Expanded form-500,000+6,000+700+9
The answer is B.
90-73=13
And what makes it one side replicates to the other side.
This making it 13.
Answer:
x ≤8/5
Step-by-step explanation:
6x - 9 ≥ 11x - 17
Subtract 6x from each side
6x -6x-9 ≥ 11x - 17-6x
-9 ≥ 5x- 17
Add 17 to each side
-9+17≥ 5x - 17+17
8≥ 5x
Divide each side by 5
8/5≥ 5x /5
8/5≥ x
