Answer:
The solution of the inequality is [tex](-2.5,\infty)[/tex].
Step-by-step explanation:
The given inequality is
[tex]-3x<7.5[/tex]
If an inequality divided by a negative number,then the sign of inequality change. Divide both sides by -3.
[tex]\frac{-3x}{-3} >\frac{7.5}{-3}[/tex]
[tex]x >-2.5[/tex]
Therefore the solution of the given inequality is all real numbers greater than -2.5.
In interval notation it can be defined as
[tex](-2.5,\infty)[/tex]
