$k=\frac{x}{5}$

Step-by-step explanation:

The width of the pre-image = x

The width of the image= 5 inches

Let 'k' be the scale factor for the dilation.

We know that after dilation, the dimensions of pre-image multiply with scale factor to get the dimension of the image.

It gives,

$5k=x\\\Rightarrow\ k=\frac{x}{5}$

Hence, the scale factor should be $k=\frac{x}{5}$
