Write an expression to represent the length of a string in yards in terms of the string's length, x, in inches

Sergio039 [100]

Answer:

$y = \frac{x}{36}$

Step-by-step explanation:

Given

Length of string = x inches

Required

Determine the length in yards

Represent the equivalent length with y

Such that

$y = x\ inches$

Divide x by 36 to get equivalent in yards

$y = \frac{1}{36} * x$

$y = \frac{x}{36}$

Hence, the equivalent in yards is $\frac{x}{36}$
