Evaluate the expression at specific values of their variables. Evaluate

24 divided a + b, when a = 6 and b 12. =

To evaluate the expression 24 divided by a + b, when a = 6 and b = 12, we substitute the values of a and b into the expression.

So, the expression becomes:

24 / (6 + 12)

We can simplify the expression inside the parentheses:

24 / 18

Now, we can divide 24 by 18:
