Question

Evaluate the expression.
r = 3
i=8
5r-i+4

Answer 1

Given r = 3 and i = 8, substitute these values into the expression 5r - i + 4:

5 * 3 - 8 + 4

Now, perform the multiplication and addition/subtraction:

15 - 8 + 4

Finally, perform the subtraction and addition:

7 + 4

This gives us:

11

So, when r = 3 and i = 8, the value of the expression 5r - i + 4 is 11.
