In an aquarium would you consider any group of organism to be primary importance? why or why not?

it's unlikely a majority of a large population would agree on issues

hope this : )

answer; /// i believe that the correct answer is (50%);

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
