Question

Which of the following is not equivalent to the formula d = rt? (5 points) Select one: a. d over r = t b. r = dt c. d over t = r d. d over rt = 1

Answer 1

the formula d = rt

r = d/t (c. d over t = r)
t = d/r (a. d over r = t)
d = rt (d. d over rt = 1)

so answer
b. r = dt ......not equivalent to the formula d = rt

Answer 2

Answer:

a,c and d.

Step-by-step explanation:

a. $\frac{d}{r}=t$ is equal to

$d=rt$ multiplying both sides by r.

b . $r=dt$

$\frac{r}{d}=t$ is different to $\frac{d}{r}=t$.

c. $\frac{d}{t}=r$ is equal to

$d=rt$ multiplying both sides by t.

d. $\frac{d}{rt}=1$ is equal to

$d=rt$ multiplying both sides by rt.
