Final answer:
To reconstruct the missing parts of the problem, we can determine the distance between x and the mess of ice cream, which is 10 units. However, the exact value of the mess of ice cream cannot be determined without more information.
Step-by-step explanation:
To reconstruct the missing parts of the problem, we need to determine the distance between x and the mess of ice cream as well as the value of the mess of ice cream. Since Ariel's answers are x = -3 and x = 7, we can infer that the distance between x and the mess of ice cream is 10 units (7 - (-3) = 10). However, without more information, we cannot determine the exact value of the mess of ice cream.
