Answer:
27
Step-by-step explanation:
⅙ × 54 = ⅓ × x
9 = x/3
x = 27
To find the mean (average), u add up all ur numbers, then divide by how many numbers there are.
mean = (5 + 12 + 1 + 5 + 7) / 5 = 30/5 = 6
To find the mode (and there does not have to be one)...u find the number that is used the most. That number would be 5...because it is used twice, whereas, the other numbers are just used once.
I would substitute y = x^2
4y^2 -21y+20=0
