Question

Which expression represents the number of feet that are in x yards?

A) 12x
B) 36x
C) 3x
D) 8/3

Answer 1

c

I think that this is the correct answer

Answer 2

we know that

`1\ yard=3\ feet`

Let

y-------> the number of feet that are in x yards

by proportion

Find the value of y

`(3)/(1) (feet)/(yard)=(y)/(x) (feet)/(yards) \\ \\y=3x\ feet`

therefore

the answer is the option C

`3x`
