Answer:

D. 9

Step-by-step explanation:

When you add 1 + 4 + 5 + 5 + 5 + 6 + 9 + 10 + 10 + 11 + 12 + 12 + 15 + 15 + 15 = 135. Which is all of the numbers given to you, and since mean is when you add all of the numbers together, and than divide it by the amount of numbers there, you will take that 135 and divide it by 15. 135 / 15 = 9. Which gets you to finally getting an answer of 9. so D. 9 is correct.

Hello!

What you would need to do first is distribute the numbers inside the parenthesis.

6(t - 3) = 2(9 - 2t)
6t - 18 = 18 - 4t

Now that they've been distributed, you need to move all variables to one side, preferably to the left as it would make it easier to read and t would be positive.

6t - 18 = 18 - 4t
10t = 36

All that is left is to divide by 10 in order to leave t alone.

t = 3.6 or 18/5
