Question

Consider the three thermometers shown in the image.  Which of the following equations correctly represents the equation relating reading on the A thermomter to the B thermometer?

Quizplus · Accepted Answer

Looking at the three thermometers, we see that A and B have the same scale, but B starts at -10 degrees Celsius while A starts at -20 degrees Celsius. To convert from A to B, we need to add 10 degrees Celsius to the reading on A. Therefore, the correct equation is B = A + 10, which is represented by option B.
