Answer:

There are 6 red marbles in Bag A.

Step-by-step explanation:

<u>Bag A</u>

Red to white marble ratio is 1:3

White to blue marble ratio is 2:3

If we match the amount of white marbles between both ratios we can put together a three-term ratio.

Red to White 2:6

White to Blue 6:9

Red to White to Blue 2:6:9

Then, the total amount of marbles in bag A is given by:

A= 2·x + 6·x + 9·x

<u>Bag B</u>

B= 1·x + 4·x

White marbles

Since the two bags contain 30 white marbles:

30=A_W+B_W= 6·x + 4·x=10x ⇒ x=3

Then,

A_R:red marbles in bag A

A_R=2·x=2·3=6

There are 6 red marbles in Bag A.
