Question

Evaluate - xyz if x = -8.4, y = 0.25, and z =3 4/5 Write your answer in simplest form.​

Answer 1

To find the value of -xyz with x = -8.4, y = 0.25, and z = 3 4/5, first convert z to an improper fraction (19/5), then multiply the values together and apply the negative sign, resulting in 33.6.

Step-by-step explanation:

The student has asked to evaluate -xyz given the values x = -8.4, y = 0.25, and z = 3 4/5. To solve this, we first convert the mixed fraction for z into an improper fraction: 3 4/5 = 19/5. We then multiply all the values together and apply the negative sign:

-xyz = -(-8.4) × (0.25) × (19/5)

First, we simplify 19/5:

-xyz = -(-8.4) × (0.25) × (3.8)

Next, perform the multiplication:

-xyz = -( -33.6)

The negative signs cancel each other out, thus the final answer is:

33.6
