To determine how many pounds are in [tex]\( x \)[/tex] kilograms, we need to use the conversion factor provided: 2.2 pounds in 1 kilogram.
The conversion can be done by multiplying the number of kilograms [tex]\( x \)[/tex] by the conversion factor (2.2 pounds/kilogram). This calculation gives us the total number of pounds in [tex]\( x \)[/tex] kilograms.
Here's the step-by-step process:
1. Identify the conversion factor:
[tex]\[ 1 \text{ kilogram} = 2.2 \text{ pounds} \][/tex]
2. If you have [tex]\( x \)[/tex] kilograms, then to convert this into pounds, multiply [tex]\( x \)[/tex] by the conversion factor (2.2 pounds/kilogram):
[tex]\[ \text{Number of pounds} = x \times 2.2 \][/tex]
So, the number of pounds in [tex]\( x \)[/tex] kilograms is given by:
[tex]\[ 2.2x \][/tex]
Thus, the correct answer is:
[tex]\[ \boxed{2.2 x} \][/tex]
