Answer:
9/29 or about 31%
Step-by-step explanation:
6+3=9 6+3+7+16=29 so 9/29 (have a great time finishing the rest of your work) :)
9/16
Since it is asking for the probability for red or black, you add the amount of black and red marbles. Since there are 16 marbles in total, the probability as a fraction would be part/whole so the fraction is written 9/16
membership fee per month = $27
membership fee x month = 27 * x = 27x
y = 117 + 27x
¢40 or $0.40
270 - 250 = 20
20 ÷ 50 = 0.4
