Question

Which equation is not equivalent to the formula r = st?

s equals r over t

t equals r over s

s equals t over r

r = ts

Answer 1

s=r/t not t/r so the third one is wrong

Answer 2

you can automatically rule out D
now set it equal to each variable:\[r=st\]\[s={r\over t}\]\[t={r\over s}\]

Answer 3

now out of your choices -A, B, and C- which is not equivalent?

Answer 4

A

Answer 5

Is it a

Answer 6

no?

Answer 7

nope, try again

Answer 8

s=r/t r=ts
t=r/s r=ts
s=t/r rs=t

Answer 9

then its b

Answer 10

i gave you all the equivalents, tell me which one is not an equivalent

Answer 11

B says \(t=\large {r\over s}\)..i told you \(t=\large{r\over s}\)

Answer 12

?

Answer 13

r = st
r/t = s
r/s = t

1. correct
2. correct
3. incorrect
4. correct
