To find out how many pounds there are in [tex]\( x \)[/tex] kilograms, we use the given conversion factor: [tex]\( 1 \)[/tex] kilogram is equal to [tex]\( 2.2 \)[/tex] pounds.
We can set up the relationship as a direct proportion:
[tex]\[
\text{Number of pounds} = 2.2 \times \text{Number of kilograms}
\][/tex]
In this case, we want to convert [tex]\( x \)[/tex] kilograms to pounds. Therefore, we multiply [tex]\( x \)[/tex] by 2.2:
[tex]\[
\text{Number of pounds} = 2.2 \times x
\][/tex]
So, the correct answer is:
[tex]\[
2.2 x
\][/tex]
Therefore, the second option ([tex]\( 2.2 x \)[/tex]) is the right one.
