Nina checks the temperature at 11:00 am. If it rises by 6 more degrees, it will break the record high temperature for that date, which is 84 degrees. If t is the temperature in degrees at 11:00 am, which mathematical sentence expresses the information above?

Final answer:

The mathematical sentence that expresses the information given is t + 6 = 84, where t represents the temperature at 11:00 am. Solving this equation gives us t = 78 degrees, which is the temperature recorded by Nina at 11:00 am.

Step-by-step explanation:

To express the information given in the question mathematically, we can set up an equation. If t is the temperature at 11:00 am that Nina checks, and knowing that an increase by 6 degrees would break the record high of 84 degrees, we write:

t + 6 = 84

This equation means that if we add 6 degrees to the temperature at 11:00 am (t), it will equal the record high temperature of 84 degrees. To solve for t, we simply subtract 6 from both sides of the equation. Therefore, the temperature at 11:00 am according to the equation would be:

t = 84 - 6

t = 78 degrees

So, Nina recorded a temperature of 78 degrees at 11:00 am.
