Evaluate a divided by b + ab - 8.

a = 21
b = 3

1 answer

To evaluate "a divided by b + ab - 8" with a = 21 and b = 3, we substitute the values of a and b into the expression:

21 divided by 3 + (21 * 3) - 8

Simplifying further:

7 + 63 - 8

Now we can add and subtract to get the final result:

(7 + 63) - 8 = 70 - 8 = 62

Therefore, when a = 21 and b = 3, the expression "a divided by b + ab - 8" equals 62.
