To determine how many pounds are there in [tex]\( x \)[/tex] kilograms, we start with the information that 1 kilogram is equivalent to 2.2 pounds.

Let's denote the number of kilograms as [tex]\( x \)[/tex]. To find the number of pounds in [tex]\( x \)[/tex] kilograms, we use the ratio provided:

1 kilogram = 2.2 pounds

Thus, to find out how many pounds are there in [tex]\( x \)[/tex] kilograms, we can set up the following relationship:

[tex]\[ \text{Number of pounds} = 2.2 \times \text{Number of kilograms} \][/tex]

Since the number of kilograms is [tex]\( x \)[/tex], the equation becomes:

[tex]\[ \text{Number of pounds} = 2.2 \times x \][/tex]

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

Among the given options:
[tex]\[ \frac{x}{2.2} \][/tex]
[tex]\[ 2.2 x \][/tex]
[tex]\[ 2.2 + x \][/tex]
[tex]\[ \frac{2.2}{x} \][/tex]

The correct option that represents the number of pounds in [tex]\( x \)[/tex] kilograms is [tex]\( 2.2x \)[/tex].

Hence:
[tex]\[ \boxed{2.2x} \][/tex]
