Final answer:
To represent the possible temperatures of the interior of the iceberg, write a compound inequality: -4°F ≤ x ≤ 5°F.
Step-by-step explanation:
To represent the possible temperatures of the interior of the iceberg, we can write a compound inequality. Let's say that x represents the temperature in degrees Fahrenheit. From the given information, we know that the temperature is between -20°C and -15°C. We can convert these temperatures to degrees Fahrenheit to get a compound inequality.
We know that -20°C is equivalent to -4°F and -15°C is equivalent to 5°F. So, the compound inequality would be -4°F ≤ x ≤ 5°F.
This means that the possible temperatures of the interior of the iceberg range from -4°F to 5°F.
