Final answer:
To represent different situations with integers, a gain of 45 meters is +45, 15 degrees below zero is -15, an elevation of 1,050 feet is +1,050, and a profit of 50 pesos is +50.
Step-by-step explanation:
The student's question involves writing integers to represent different situations. Here's how the situations can be represented as integers:
- a) A gain of 45 meters can be represented by the positive integer +45, as a gain implies an increase.
- b) 15 degrees below zero is represented by the negative integer -15, which indicates a temperature below the zero point.
- c) An elevation of 1,050 feet is a positive measurement and thus is represented by the positive integer +1,050.
- d) A profit of 50 pesos can be represented by the positive integer +50 since profit indicates an increase in money.
Applying this approach helps to translate real-world situations into mathematical expressions using integers.
