Sagot :

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.
