Answer
The solution is $x\lt -0.25$.
The graph is shown below.
Work Step by Step
The given inequality is
$\Rightarrow -20x\gt 5$
Divide each side by $-20$. Reverse the inequality symbol.
$\Rightarrow \frac{-20x}{-20}\lt \frac{5}{-20}$
Simplify.
$\Rightarrow x\lt -\frac{1}{4}$
$\Rightarrow x\lt -0.25$
Hence, the solution is $x\lt -0.25$.
Use an open circle because $-0.25$ is not a solution.
Shade the number line on the left side.
