Victoria saw on the weather report that Alaska’s temperature was 17 degrees below zero. Represent the temperature as an integer. The temperature in Cape Town can be represented by the opposite of this integer. What is the temperature in Fahrenheit in Cape Town?
The temperature in Alaska was 17 degrees below zero. This means we need to subtract 17 from zero. Zero minus 17 is equal to negative 17. Therefore, the temperature in Alaska represented as an integer is negative 17.
The second part of the question tells us that the temperature in Cape Town is the opposite of this integer. This means that negative 17 plus 𝑥, the temperature in Cape Town, equals zero.
Adding 17 to both sides of this equation gives us 𝑥 equals 17. This means that the temperature in Cape Town is 17 degrees Fahrenheit.
