Answer
$w\leq -32$
The graph is shown below.
Work Step by Step
The given inequality is
$\Rightarrow -6.4\geq \frac{1}{5}w$
Multiply each side by $5$.
$\Rightarrow 5\cdot (-6.4)\geq 5\cdot \frac{1}{5}w$
Simplify.
$\Rightarrow -32\geq w$
Hence, the solution is $w\leq -32$.
Use a close circle because $-32$ is a solution.
Shade the number line on the left side.
