I am to mental for this math... XD plz h e l p

Answer:
a ≥ [tex]-\frac{64}{3}[/tex]
Step-by-step explanation:
You would solve this exactly as if the ≥ sign was an equal sign:
[tex](\frac{3}{4} )a[/tex] ≥ [tex]-16[/tex] [Given]
3a ≥ -64 [Multiply 4 on both sides of the sign]
a ≥ [tex]-\frac{64}{3}[/tex] [Simplify]
Hope this helps! I apologize if I'm incorrect
