Answer:

The range of $\frac{8}{3}-5mx$ is (-9,-3).

Step-by-step explanation:

The given compound inequality is

$9$

We need to find the range of values of $\frac{8}{3}-5mx$ .

Let $y=\frac{8}{3}-5mx$

Divide each side of the given compound inequality by 3.

$\frac{9}{3}$

$3$

Multiply each side by -1.

If we multiply an inequality by a negative number, then the sign of inequality is changed.

$3(-1)>(5mx-\frac{8}{3})(-1)>9(-1)$

$-3>-5mx+\frac{8}{3}>-9$

$-3>\frac{8}{3}-5mx>-9$

$-3>y>-9$

Therefore the range of $\frac{8}{3}-5mx$ is (-9,-3).
