Answer :- b) x ≥ 24

Solution :-

We can write the problem presented in the form of an inequality:

  • [tex]\bf \dfrac{x}{2}+8\geq20[/tex]

Now, we can proceed to its solution:-

[tex]\qquad[/tex] [tex]\pink{\twoheadrightarrow\bf \dfrac{x}{2}+8\geq20}[/tex]

[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf \dfrac{x}{2}\geq20-8[/tex]

[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf \dfrac{x}{2}\geq12[/tex]

[tex]\qquad[/tex] [tex]\pink{\twoheadrightarrow\sf x\geq24}[/tex]

  • Henceforth,Option b) x ≥ 24 is correct.
