To evaluate the expression for r = -3 and s = 5, we substitute -3 for r and 5 for s.
Therefore, the expression becomes:
3(-3) / 5 - 2
Simplifying:
-9 / 5 - 2
Multiplying the -9 and 2 by 5 to have a common denominator:
-9 / 5 - 10 / 5
Combining the fractions:
(-9 - 10) / 5
-19 / 5
So, the evaluated expression is -19/5 or -3.8.
The correct answer is -3.8
