To determine how many pounds correspond to [tex]\( x \)[/tex] kilograms given the conversion rate of 2.2 pounds per kilogram, follow these steps:

1. Understand the conversion rate:
- You know that 1 kilogram is equivalent to 2.2 pounds.

2. Set up the relationship:
- For [tex]\( x \)[/tex] kilograms, the number of pounds can be calculated by multiplying [tex]\( x \)[/tex] by the conversion rate, which is 2.2.

3. Set up the equation:
- To find the weight in pounds for [tex]\( x \)[/tex] kilograms, use the equation:
[tex]\[ \text{pounds} = 2.2 \times x \][/tex]

4. Write the expression:
- Substituting the value [tex]\( x \)[/tex], the expression becomes:
[tex]\[ 2.2x \][/tex]

So, the number of pounds corresponding to [tex]\( x \)[/tex] kilograms is given by the expression [tex]\( 2.2x \)[/tex].

Therefore, the correct answer from the given options is: [tex]\( 2.2x \)[/tex].
