All of the following are equivalent except _____.d = rt
dt = r
d /t = r
d/r = t

Answers

The expression which is not equivalent to other three is dt = r

What is an expression?

Numbers, symbols and operators grouped together that show the value of something.

Given are the four expressions, d = rt, dt = r, d /t = r, d/r = t

2) dt = r

d = r/t

3) d/t = r

d = tr

4) d/r = t

d = rt

Hence, we can say the expression dt = r is unequal to the other three.

& 50 - 6% = 47 


& 50 * 6% = 3
I think i helped you :-)
47/50 
multiply by 2 both sides

NEED help plz!

Answers

So since the problem says the number 46 is equal to something, you immediately know that your equation will look like this

46 = something

Now, when an unknown number is multiplied by a number, it has the number and a letter right next to it.

example.  23p

So since 23p = 46, your answer is B :) Hope this helped!
it's B because p is used as the unknown number here and some ways of saying multiplication is
23 x p
23 (dot in the middle) p
or 23p
since the qw says the number 46 is equal to it is
46=
so the answer is B) 46=23p
