A) y = 3 /20 x
B) y = 60x
C) z = 20xy
D) y = 60/x

PLZ HELP !

Answer 1

Answer:

D)

Step-by-step explanation:

We know that it cannot be C since z is not involved in this problem.

a) 3/20x

Try with 20 = x

3/440 ≠ 3

A is not the answer.

b) 60x

Try with 20 = x

1800 ≠ 3

B is not the answer.

c) 60/x

Try with 20 = x

3 = 3

Try with 15 = x

4 = 4

D is your answer.

Hope this helps. Have a nice day. Oh, and one more thing. Surprised to see I'm not stealing points?
