Evaluate the expression for r = -3 and s= 5.

3r over s -2

1 answer

First, let's substitute the values of r and s into the expression:

3r/s - 2

= 3(-3)/5 - 2

= -9/5 - 2

To combine these fractions, we need a common denominator (5 in this case).

= (-9 - 10)/5

= -19/5

Therefore, the value of the expression when r = -3 and s = 5 is -19/5.
