Answer:
-48+-12=. -60
Step-by-step explanation:
Well -48 +( -12)
Assume the plus sign is +1 ,multiply by 12 using the law of integers. that is +(-)= -. Then continue by subtracting -12 from - 48. with this another law is used -(-)= a plus . Like 48 + 12 =60.Then check for the number with the highest value to determine your answer for the sum you got. In this case negative 48 is the highest so it's negative 60
Answer:
Step-by-step explanation:
We are to rank the options given in the question to correctly prove the theorem that: "If A & B are set, and A is a subset of B"
To arrange the steps in the correct order, we have:
(a) Assume that B is countable
(b) The elements of B can be listed as b1, b2, b3
(c) Since A is a subset of B, taking the subsequence of {bn} that contains the terms that are in A gives a listing of the elements of A.
(d) Therefore A is countable, contradicting the hypothesis.
(e) Thus B is not countable
A is the answer Bc I did this before and my teacher said I did an excellent job!
