Answer:
60 hand shakes.
Step-by-step explanation:
We have been given that there are 6 married couples at a party.
This means there are 12 people in total.
We know that number of handshakes for n people is given by formula 
.
We are also told that at the start of the party every person shakes hands once with every other person except his or her spouse.
So formula for this problem would be 
or 
.
Since total numbers of people is party is 12, so we will get:
Therefore, there will be 60 hand shakes at the party.
False, both lines are oblique (diagonal) so they meet at some point on a graph. They can only have no solutions if the lines are parallel/have the same slope.
Team B because mode is how often a number appears in a list and 60 is greater than 48 or 30, which are the modes of Team A and Team C
Hope this helps!
Answer:
x<3
Step-by-step explanation:
We divide equation by 3. So we get x<3. You can think of it with logic, too.
Answer: b+95+34=180, b+129=180, 51
Step-by-step explanation:
b+95+34=180 works because the angles add to form a straight angle.
From this, we can obtain b+129=180 by adding the two constants.
Subtracting 129 from both sides, we get b=51.
