Question

Evaluate the expression for the given value(s) of the variable(s). $$\frac{x}{5}-2 y \text { when } x=12 \text { and } y=\frac{4}{5}$$

Short answer

The evaluated expression equals \(0.8\)

Step-by-step solution

Substitute the given values

Substitute \(x = 12\) and \(y = \frac{4}{5}\) into \(\frac{x}{5}-2 y\), which results to \(\frac{12}{5}-2 (\frac{4}{5})\)

Perform the Division

First perform the division operation inside the brackets to get \(\frac{12}{5}-2(0.8)\). The result is \(2.4-2(0.8)\).

Perform the Multiplication

Perform the multiplication operation to get \(2.4-1.6\).

Perform the Subtraction

Finally perform the subtraction operation to get \(0.8\).
