Final answer:
The equation that shows the relationship between a number (x) and its sum is 13x = 62.
Step-by-step explanation:
The equation that shows the relationship between a number (x) and its sum is option 2) 13x = 62.
To understand why, let's break down the equation:
13x = 62
The coefficient 13 represents the number being added to x.
The x represents the unknown number we're trying to find.
The equal sign (=) represents the relationship between the sum of the number and 62.
Finally, the number 62 represents the sum of the unknown number and 13.
Therefore, option 2) 13x = 62 is the equation that shows the relationship between a number (x) and its sum.
