Final answer:
To evaluate the expression 10g + 9a - 2 with g = 8 and a = 11, substitute the values into the expression and calculate the result of 177.
Step-by-step explanation:
To evaluate the expression 10g + 9a - 2 when g = 8 and a = 11, we substitute the values of g and a into the expression.
So the expression becomes: 10(8) + 9(11) - 2.
Calculating this expression gives us a result of 80 + 99 - 2 = 177.
