Given:
If x, y, and z are positive integers, then
To find:
The value of 
.
Solution:
First we need to find the prime factors of 54000.
...(i)
We have,
...(ii)
On comparing (i) and (ii), we get 
.
The sum of 
is:
Therefore, the value of is 10.
She has no more white ribbon because she exchanged it for yellow.
X+y=6
x=10
10+y=6
y=-4
10=-4+z
-4+z=10
z=10+4
z=14
So the correct answer is 14
I'm assuming we need to simplify this expression. (Tip when you are writing n squared, please write n^2, not n2.)
Since we can see that there is a 5 in each term inside the ( ), we simplify have to remove that if the whole thing is going to be divided by 5.
Answer:
(15n^2-5n+45)/5
=3n^2-n+9
Total Score = 10*85=850
Final total after throwing out top and bottom scores = 850-60-92
=698
Therefore Final Average
= 698/8
=87.25
