The temp. was 72 degrees F at noon. At midnight, the temp. dropped to 12 degrees F. Write an algebraic expression to find the sum.
sum is 72+12
but who ever needs the sum of temperatures? More likely you want to know how far the temperature fell: 72-12 degrees
To find the sum of the temperatures at noon and midnight, we can use the algebraic expression:
Temperature at noon + Temperature at midnight
Let's assign variables to represent the temperatures.
Let Tn represent the temperature at noon.
Let Tm represent the temperature at midnight.
Using these variables, the algebraic expression to find the sum is:
Tn + Tm
In this specific scenario, the temperature at noon is 72 degrees Fahrenheit (°F) and the temperature at midnight is 12 degrees Fahrenheit (°F).
So, substituting these values into the expression, we have:
72 + 12
Therefore, the sum of the temperatures at noon and midnight is 84 degrees Fahrenheit (°F).
