Question

Evaluate the expression y - x + z for x = 4.5, y = 6, and z = 0.47

a) 2.03
b) 1.03
c) 0.53
d) 1.53

Answer 1

To evaluate the expression y - x + z given the values x = 4.5, y = 6, and z = 0.47, substitute the values and perform the operations to find the result is 1.97.

Step-by-step explanation:

To evaluate the expression y - x + z with the given values for x, y, and z, we simply substitute the numbers into the expression and then perform the arithmetic operations:

y - x + z = 6 - 4.5 + 0.47

We first subtract x from y:

6 - 4.5 = 1.5

Next, we add z:

1.5 + 0.47 = 1.97

Therefore, the value of the expression y - x + z when x = 4.5, y = 6, and z = 0.47 is 1.97.
