This is a question of combination. In other words, the question requires determination of number of ways in which 12 appetizers can be chosen form a total of 17 appetizers.
Therefore,
Possible number of 12 groups = 17C12 = 17!/[12!*(17-12)!] = 6188
A) -180m
b) 510-180=+330m
+330/45=7.333m/s
c) total distance = 840m
average speed = 840/105
= 8m/s
Step-by-step explanation:
a. 2(y-8)
= 2y-16
b. 3(x-5)
= 3x-15
c.6(b-4)
= 6b-32
d.7(d-2)
= 7d-14
e.5(2-y)
= 10-5y
f.3(4-t)
= 12-3t
g.5(b-a)
=5b-5a
h.7(2-h)
= 14-7h
Answer:
it's a bit blurry but if I aint wrong it's the 2nd one that say 2/5
