All you have to do to solve this problem is insert the integer for the variable in the expression.
So, instead of having the variable expression r+s+t, you would have the integer expression 26-12-8.
If you combine 26 and -12, you get 14-8.
If you subtract 14-8, you get 6.
Your final answer is a. 6.
9 degrees
because 12/4 = 3 degrees (per 1000 feet)
3 x 3 = 9 degrees total (in 3000 feet)
hope this helps
