Answer:
10
Step-by-step explanation:
35/7 = 5, so the white marbles appears 5 times often.
If we have 2 green marbles and we want to maintain the same ratio of green to white marbles (so the same assumption that white appears 5 times often) we need to multiply that by 5.
18m?
45 feet would be the answer.

5! and 6p3
5! = 5*4*3*2*1 = 120
6p3= n!/(n-r)!
where n = 6
and r = 3
6p3 = 6!/(6-3)!
= 6*5*4*3*2*1/3*2*1
= 120
