Answer:
3/9
Step-by-step explanation:
because there are total 9 marbles. 3 red, 4 green and 2 blue.so the probability is 3/9.
108=3(b-s)
36=b-s
s=b-36
...
108=2(b+s), and using s found above gives us:
54=b+b-36
54=2b-36
2b=90
b=45, and since s=b-36, s=9
So the boat's speed is 45mph and the stream's speed is 9mph
V=2
First you need to divide both sides by -6
Then move the 1 subtracting
Then divide both sides by -5
