Mean is the average. to find mean, you add all the numbers and divide it by how many numbers there are.
68 + 75 + 85 + 80 + 75 + 82 = 465
There are 6 numbers. That means you have to divide 465 by 6 to get the mean.
Divide:
465 / 6 = 77.5
The answer is D. 77.5

Answer:
552
Step-by-step explanation:
23x + 4y when x=20 and y=23
if x=20 and y=23 all you have to do is replace the numbers and solve
23(20) + 4(23)
Multiply 23*20 which is equal to 460
Then you multiply 4*23 which is equal to 92
The problem is now 460 + 92
add it, and you get 552.
Hope this helps!!
