3. two units of measurement for weight are pounds and kilograms. use the image below to help you create a…

Explanation:

Step1: Observe the scale

From the scale, when the pointer points to 0 kg, it points to 0 lb; when it points to 1 kg, it points to 2.2 lb. We can establish a conversion - formula. The relationship between pounds ($p$) and kilograms ($k$) is a linear relationship of the form $p = mk + b$. When $k = 0$, $p=0$, so $b = 0$. When $k = 1$, $p = 2.2$, so $m=2.2$. The conversion formula is $p = 2.2k$.

Step2: Reverse - conversion formula

To convert from pounds to kilograms, we solve the equation $p = 2.2k$ for $k$. We get $k=\frac{p}{2.2}$.

Answer:

To convert from kilograms ($k$) to pounds ($p$), use the formula $p = 2.2k$. To convert from pounds ($p$) to kilograms ($k$), use the formula $k=\frac{p}{2.2}$.
