First , in order to find the answer you need to add the add the numerators which are 5 and 2 = 7 and then you need to find a common denominator.
Answer:
c)The proof writer mentally assumed the conclusion. He wrote "suppose n is an arbitrary integer", but was really thinking "suppose n is an arbitrary integer, and suppose that for this n, there exists an integer k that satisfies n < k < n+2." Under those assumptions, it follows indeed that k must be n + 1, which justifies the word "therefore": but of course assuming the conclusion destroyed the validity of the proof.
Step-by-step explanation:
when we claim something as a hypothesis we can only conclude with therefore at the end of the proof. so assuming the conclusion nulify the proof from the beginning
960 beads are used to make the necklace.
192 x 5 = 960, so that's how i got my answer and then you just divide to check if it's right or not.
