marbles? A) 2b, where b represents the number of blue marbles. B) 2r,
wherer is the number of red marbles C) r+2, wherer is the number of red
marbles D) b2, where b is the number of blue marbles *

Answer 1

I'm pretty sure its 2r, because you are multiplying the number of red marbles by 2 to get how many blue marbles there are.
