What is the expression and value of "six less than the quotient of a number and two, increased by ten" when n = 8? 0-6+ 18 when n = 8, the value is 8.
0 6-5+10; when n = 8, the value is 12.
02-6+10; when n = 8, the value is 11.
6- +10; when n = 8, the value is 9.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

step-by-step explanation:
