The answer is N because it you cut in half vertically or horizontally, the two halves won't match. Even though T cannot be cut in half horizontally, it can still be cut vertically.

If n(A-B)=18,n(AuB)=70 and n(AnB)=25 then find n(B)

svp [43]

n(A-B) denotes elements which are in A but not in B

n(Au B) denotes elements in A and B

n(AnB) denotes elements that are common in A and B

Now I will add one more set

n(B-A) which denotes elements in B but not in A

So, n(AuB) = n(A-B) + n( B-A) +n(AnB)

70 = 18 +n(B-A) + 25

70 = 43 + n(B-A)

n(B-A) = 70-43

n(B-A) = 27

So, n(B) = n( B-A) + n( AnB)

= 27+25

= 52

The sum of A and B is 171 and their difference is 35. What are the numbers?

Answer:

103 and 68

Step-by-step explanation:

since the difference has to be 35 subtract 35 from 171 (equals 136) then divide it by 2, you get 68 which is your first number, then add 35 back and get 103 for the second number, I hope this helped

Gennadij [26K]

This can be accomplished using addition. If time starts at 5:47, and it takes 33 minutes to get from Point Pleasant to Long Branch, then it is now 6:20.
After you arrive, you waited 14 minutes. It is now 6:34. Finally, it's an hour and 20 minute journey from Long Branch to New York. The final time is 7:54.

Hope this helps!
