If 8/x= 160, what is the value of x ?...

If `8/x= 160`, what is the value of x ?

A

1280

B

80

C

20

D

`0.05`

Text Solution

Verified by Experts

The correct Answer is:
D
Multiplying both sides of the given equation by x yields 160x = 8. Dividing both sides of the equation 160x = 8 by 160 results in x = `8/160`.Reducing `8/160` to its simplest form gives `x=1/20`, or its decimal equivalent 0.05.
Choice A is incorrect and may result from multiplying, instead of dividing, the left-hand side of the given equation by 160. Choice B is incorrect and may result from a computational error. Choice C is incorrect. This is the value of `1/x `.
