Question

Evaluate the expression when w=4,x=-11.7, and z = -5.4

Answer 1

I'm not sure but it might be 21.1 (I think)

Answer 2

Answer: I can't read the attached photo well, so I will assume the following:

Equation: w + x -z

Values: w=4, x=-11.7, z = -5.4

If so, the answer is -2.3

Explanation:

4 -11.7 -(-5.4) = -2.3
