Answer:
The numbers are 31 and 15. Add to get a sum of 46, and subtract to get a difference of 16.
Step-by-step explanation:
Since |-4|=4 and |5|=5
from lowest to highest,
-7, 2, |-4|, |5|
56 + c = 83 equation
subtract 56 from each side
c = 27
c cannot equal 33
Answer:
14365
Step-by-step explanation:
If there are 170 people, total, then each one shakes hands with 169 other people.
You’d think that would mean 170 x 169 handshakes, or 28730. But each handshake counts twice, because two people are involved, right? So you need to divide that number by two.
(This works because handshaking is commutative — if I’m shaking your hand, then you’re shaking my hand. If we used some other action that was not commutative, such as giving a punch to the nose, then the answer would indeed be 28730.)
So take that number and divide it by two.
