Final answer:
The correct equation to represent the temperature in Knowlton, which is 12°C warmer than Elmwood, is B: 5 + 12 = 17, assuming Elmwood's temperature is 5°C.
Step-by-step explanation:
The question involves creating an equation that expresses the relationship between two temperatures. Specifically, we are looking for the temperature in Knowlton, which is 12°C warmer than the temperature in Elmwood. To represent the temperature in Knowlton, we let TElmwood be the temperature in Elmwood. Therefore, the temperature in Knowlton is TKnowlton = TElmwood + 12°C. Looking at the options provided by the student, option B states 5 + 12 = 17, which is the correct form of an equation representing a temperature in Knowlton that is 12°C warmer than the temperature in Elmwood, assuming the temperature in Elmwood is 5°C. Therefore, the correct answer is B: 5 + 12 = 17.
