8. Hero Group Title

By the way, the expression can also be written as $\frac{d}{2} - 10$

@hero i know

lol @Luis_Rivera

11. Hero Group Title

I wonder if you could come back here later when your teacher tells you b is incorrect.

FYI i dont think its b i think its something else

13. Hero Group Title

Actually, I'll give you the correct expression for b: $\frac{d - 10}{2}$

14. Hero Group Title

So there's no way b is the correct answer choice.

15. Hero Group Title

@Luis_Rivera, she already stated that she doesn't believe the answer is b.

I think its A

17. Hero Group Title

That's correct.
