6. 2(2b + 6j)
7. 3(2s - 5f)
8. 10c + s + 2p
9. 2a <3p
10. 5(a+b)
11. 1/2r + 3/4g

Answer:
6
Step-by-step explanation:
The answer is 6 because there is three other couples and so Barbie would have shaken each couples hand and in a couple there are two people so that would be two handshakes per couple minus Kens hand.
It is 7 thousand and a bunch of random numbers
G(x) = 3x + 2(x + 1)
g(7) = 3(7) + 2(7 + 1)
g(7) = 21 + 2(8)
g(7) = 21 + 16
g(7) = 37
