Question

Evaluate the expression: (x - y/z) given (x = 4), (y = 2/5), and (z = -4). Provide the answer as a decimal.

Answer 1

To evaluate the expression (x - y/z) with given values, we substitute them into the expression and find that (4 - (2/5) / -4) equals 4.1 when calculated step by step.

Step-by-step explanation:

To evaluate the expression (x - y/z) given (x = 4), (y = 2/5), and (z = -4), we substitute these values into the expression and calculate the result step by step:

1. First, we convert the fraction for y into a decimal, so y = 2/5 = 0.4.
2. Next, we evaluate the denominator of the fraction in the expression, which means calculating y/z. Since z is -4, we have y/z = 0.4 / -4 = -0.1.
3. Then, we substitute the values of x and the calculated y/z into the expression: x - y/z = 4 - (-0.1) = 4 + 0.1 = 4.1.

The answer as a decimal is 4.1.
