Number of red marbles in bag = r. b = 10-rProbability of first marble being red: r/10Second marble being red: (r-1)/9total probability = 2/15 = (r-1)*r/90r = 4b = 6
2x+6y=24 Explanation: $2 each meaning it’s 2 times x because we don’t know how many hoots and $6 each meaning it’s also 6 times y and then $24 is our total meaning =24 so your answer is 2x+6y=24
