<h3>Answer: 10</h3>
============================================
Work Shown:
First add up all the ages
9+13+9+10+10+9+10+10+11+9 = 100
Then divide that sum by 10, since there are 10 values we added up
100/10 = 10
The average age is 10 years old.
F(x)=2x-3
f(1/2)=2(1/2)-3
f(1/2)= 1-3
f(1/2)= -2

now you must first distribute the 2 in the brackets. multiply 2 by h and (-29)

now combine "like terms" (-58) with (-58) and 2h with (-h)

now that h has no coefficient (no number in front) you can bring the -116 over to the other side to isolate the variable (h). remember when you bring a number over the equal sign the signs change so (-116) becomes 166.

now add the two terms together

the final result is 157
