To find how many Pokemon cards Nole has, we start by understanding the given information:
Sami has 84 Pokemon cards, which is 12 times the number of cards Nole has. This can be expressed with the equation:
\[ 12c = 84 \]
Where \( c \) represents the number of cards Nole has.
If we rearrange this equation to solve for \( c \):
\[ c = \frac{84}{12} \]
This means the correct representation of how many cards Nole has would actually be:
\[ c = 84 ÷ 12 \]
However, among the provided options, none of them include this exact representation. The closest form of equation that expresses how many cards Nole has would therefore have to be:
\[ c = 84 ÷ 12 \], but since it's not listed, none of the options correctly represent the equation.
If we consider the options more closely, the correct formulation should be based on \( 12c = 84 \) meaning Nole has a certain number of cards, \( c \), which results in \( 12c \) equalling 84 when Sami has 12 times that amount.
Based on the formulas given:
- \( 12 + c = 84 \) (Incorrect)
- \( c - 12 = 84 \) (Incorrect)
- \( 12 x c = 84 \) (Correct representation of the relationship.)
- \( c ÷ 12 = 84 \) (Incorrect)
Hence, the equation that correctly represents the relationship about how many cards Nole has is:
\( 12c = 84 \), which is reflected in option ‘12 x c = 84’.
Note: Ensure to correctly interpret the options given in context with variables or if asked, you can simplify it further based on available mathematical operations.
