Let the difference between consecutive terms be D. If the middle term is 30, then the term before it is 30-D, and the term after it is 30+D. So the sum of these three terms would be (30-D) + 30 + (30+D) = 3*30.
Extending this sum to include all 11 terms centered around 30, we see that any addition of D is canceled by a balanced subtraction, leaving you with 11 copies of 30. So the value of the sum is 11*30 = 330.

Answer:
x = 77, y = 42
Step-by-step explanation:
y + 31 = 73 via parallel, y = 42
x + y + 61 = 180 via triangle angle sum, x = 77
Answer:
You can divide and see if its devided by 3, and if its not in the times table, you will have a decimal
Step-by-step explanation:
We have to assume that the intention is that S represents the set of possible outcomes.
A. TRUE — any of the faces may appear
B. false — 0 is not a possible outcome and is not in set S.
C. TRUE — {5, 6} is a subset of S
D. TRUE — A = S \{5}
E. false — even numbers are {2, 4, 6}. The complement of that includes 5, which A does not.
