Answer
43days
Step-by-step explanation:
Given that the total number of pages is 300
and Jared has read 85 pages
this means he has 300-85=215 pages unread.
We are told that if he reads 5 pages per day in how many days would he be done with the 215 pages left.
to solve for the number of days left, we have to divide 215 by 5
that is
=215/5
=43 days
So Jared needs 43 days to read the 215 pages left and return the book to the Lilbrary.
<span>This is a nasty problem. There's 12 possible arrangements of the 3 Gods and which of Ja or Da means "yes" (3!*2 = 6*2 = 12). The key thing here is the concept of a double inversion in logic. If you have a true value and pass it through 2 not gates, you'll still get a true value at the end. So you need to ask a question about a question in order to force a true answer from either god "True" or god "False". God "Random" simply adds a bit of annoyance. So your first question needs to determine the identity of a god that's not "Random".
So imagine a question of the form:
If I asked you X, would you have answered "Da"?
If you're talking to "True", there are 4 possibilities.
1. Da means "No", Ja means "Yes" and X is "No"; True would have answered X with "Da" and therefore would answer the whole question with "Ja"
2. Da means "No", Ja means "Yes" and X is "Yes"; True would have answered X with "Ja" and therefore would answer the whole question with "Da"
3. Da means "Yes", Ja means "No" and X is "No"; True would have answered X with "Ja" and therefore would answer the whole question with "Ja"
4. Da means "Yes", Ja means "No" and X is "Yes"; True would have answered X with "Da" and therefore would answer the whole question with "Da"
Key thing to notice is that no matter what the meaning of Da or Ja, the answer will always be "Ja" if X is false, and "Da" if X is true.
Now imagine the same question being asked of False
1. Da means "No", Ja means "Yes" and X is "No"; False would have answered X with "Ja" and therefore would answer the whole question with "Ja"
2. Da means "No", Ja means "Yes" and X is "Yes"; False would have answered X with "Da" and therefore would answer the whole question with "Da"
3. Da means "Yes", Ja means "No" and X is "No"; False would have answered X with "Da" and therefore would answer the whole question with "Ja"
4. Da means "Yes", Ja means "No" and X is "Yes"; False would have answered X with "Ja" and therefore would answer the whole question with "Da"
Notice that False will give the exact same answers as True. "Ja" if X is false, and "Da" if X is true.
So you won't have any idea as to meaning of Ja and Da, but you will know if question "X" is truthful or not.
First question:
Ask A:If I asked you "Is B god Random?", would you have answered "Da"?
If A is either True or False, then you know if the answer is "Da" that B might be Random, and that C is definitely NOT Random. And if the answer is "Ja", then C might be Random and that B is definitely NOT Random.
If A is Random, then it really doesn't matter, since both B and C are NOT Random.
Now your next question is going to be to either "B" or "C" depending upon the answer to the 1st question. You want to be asking the question of a God that is NOT random, so if you got the answer "Da", ask the next question of C and if you got the answer "Ja", ask the next question of B.
The second question is still of the form "If I asked you X, would you have answered "Da"?" and the same exact logic applies. If you're talking to True, the answer passed through two buffers and comes out true, and if you're talking to False, it passes through two inverters and still comes out true.
Second question:
If I asked you "Are you False?", would you have answered "Da"?
And if the answer is "Da", then the god you're speaking to is False, and if the answer is "Ja", then the god you're speaking to is "True".
Final question:
If I asked you "Is A god Random?", would you have answered "Da"?
And if the answer is "Da", then A is definitely "Random" and if the answer is "Ja", then the god you haven't spoken to is definitely "Random".
So now you know if the god you're speaking to is True or False, and you have the correct identity of Random. The 3rd god is a simple matter of elimination.</span>

using the second equation you can get s=-2. then plugging that into the first you get
-9(-2)-8 = 18-8 = 10
