Since the order of the students selected is important in this item, the concept used for this question is that of the permutation. For this item it is the "permutation of 28 taken 6". This may be mathematically expressed as 28P6. The numerical answer is 271252800. Thus, the answer is letter C.
Answer: 13
Step-by-step explanation:
if Sarah made 13 snadwhichedls all together and Chad had 6 fewer which made it 7 I believe she made 13 ssbdwhiches all together
Answer:

<em>Because</em><em> </em><em>it</em><em> </em><em>has</em><em> </em><em>it</em><em> </em><em>two</em><em> </em><em>sides</em><em> </em><em>equal</em><em> </em>
9x - y = 45....subtract 9x from both sides
-y = -9x + 45 ...multiply both sides by -1 to make y positive
y = 9x - 45 <==
To answer this question, the easier way is to make each of the mixed fractions expressed as improper fractions
Thus, we have 6 4/9 written as 58/9 ( we shall be extending this to the other fractions too; the key is to multiply the denominator by the whole number, then add the numerator)
3 2/9 would be expressed as 29/9
and finally 8 2/9 would be expressed as 74/9
So, we can rewrite the question as follows;
-58/9 - 29/9 - 74/9
We can see all have same denominator;
Thus, we can proceed to summing all the numerators.
We have;
(-58-29-74)/9 = -161/9
We then proceed to turn this to an improper fraction too;
Kindly find the nearest multiple of 9 less than 161, then subtract the value from 161;
That would be 153 and we are left with a difference of 8
So our final mixed fraction would be -17 8/9
Hence; -6,4/9 - 3 2/9 - 8 2/9 = -17 8/9
