Which equation is not equivalent to the formula d = rt? r equals t over d r equals d over t t equals d over r d = tr
Gennadij [26K]
Question restated.
which is not equivalent to d = rt?
r = t/d
r = d/t
t = d/r
d = tr
If we divide both sides of the original equation by t, we are left with r = d/t, so we know that this is true. if we compare this, however, with the first item on the list, we can see that t/d does not equal d/t, so the first item on the list is the wrong one.
