Answer:
the one possible value for x would be any non-negative multiple of 4, such as 0, 4, 8, 12, 16, and so on.
Explanation:
To determine the possible value for x, we need to consider the constraints provided. According to the information given, Melanie buys x boxes of 4 and y boxes of 10.
Since the grocery store sells tomatoes in boxes of 4 or 10, the number of tomatoes Melanie buys should be divisible by 4. Therefore, the value of x must be a multiple of 4 to ensure that only boxes of 4 are purchased.
Hence, the one possible value for x would be any non-negative multiple of 4, such as 0, 4, 8, 12, 16, and so on.
