Answer:
Option C.
Step-by-step explanation:
The given equation is
[tex]-\dfrac{5}{2}(x)-5=-55[/tex]
We need to find the value of x.
Add 5 on both sides.
[tex]-\dfrac{5}{2}(x)-5+5=-55+5[/tex]
[tex]-\dfrac{5}{2}(x)=-50[/tex]
Multiply both sides by 2.
[tex]-5x=-100[/tex]
Divide both sides by -5.
[tex]x=\dfrac{-100}{-5}[/tex]
[tex]x=20[/tex]
Therefore, the correct option is C.
