The number of handshakes is the number of ways 6 objects can be selected 2 at a time.
.. C(6,2) = 6·5/(2·1) = 15
The appropriate choice is
... C) 15
_____
Consider that each person can shake hands with 5 others. That's a total of 6*5 = 30 handshakes, but it counts both A shaking with B and B shaking with A. If each pair of persons only shakes hands once, the number of handshakes is 30/2 = 15.
The answer to this question is C
Because you are supposed to do division first following PEMDAS so 12÷2=6 then you would do 2+6=8 SO THE ANSWER IS C
Answer:
The value of x is 6
Step-by-step explanation:
Since it's a parallelogram both sides are the same so the bottom equation needs to equal 15 m, therefore 2*6+3=15.
