## anonymous 3 years ago Which equation is not equivalent to the formula r = st? A) s = r/t B) t = r/s C) s = t/r D) r = ts

1. lstrasmann

Well, the commutative property would make D be equivalent, so we can cross that out.

2. anonymous

Which ones can we cross out?

3. lstrasmann

B can also be crossed out. $r=st$$\frac{ r }{ s }=\frac{ st }{ s }$$\frac{ r }{ s }=t$
