Question

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

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

$\frac{3}{1} \frac{feet}{yard}=\frac{y}{x} \frac{feet}{yards} \\ \\y=3x\ feet$

therefore

the answer is the option C

$3x$
