Question

The temperature in your town is 43°F. The radio announcer says that the temperature will drop 15 degrees. Write an expression to compute the predicted temperature. What will the temperature be?

A. 15 + (–43);
B. –28°F43 + 15;
C. 34°F15 + 43;
D. 58°F43 + (–15);
E. 28°F

Answer 1

The predicted temperature is 28°F.

Step-by-step explanation:

Temperature is a measure of the average kinetic energy of the particles in a substance. It provides an indication of how hot or cold a substance is. Temperature is typically measured using various scales, and the three most common scales are Celsius (°C), Fahrenheit (°F), and Kelvin (K).

To compute the predicted temperature, we need to subtract 15 degrees from the current temperature of 43°F. The correct expression to calculate the predicted temperature is option D. So, the temperature will be 43 + (-15), which gives us a predicted temperature of 28°F.
