Step-by-step explanation:
A. b x 30 = 7E. b x 7 =30C. b = 30 + 7
So the ratio 3:9 can be added together to make twelve. Add the number set together 3 times to get 36. Now you have 3+9 3+9 3+9. 3=blue so you will need nine blue pens and 27 red pens.
Answer:
P(1 and 2 are green) = 3/25
Step-by-step explanation:
We need to know the total number of marbles
6 Blue + 10 red + 9 green = 25 marbles
P ( 1st marble is green) = green/ total
= 9/25
Since we don't put it back, there are
6 Blue + 10 red + 8 green = 24 marbles
P ( 2st marble is green) = green/ total
= 8/24 = 1/3
P(1 and 2 are green) = P(1st green) * P(2nd green)
= 9/25 * 1/3
= 3/25
