Answer 1

Question:

One day the temperature started at -6°F and dropped 16° by the end of the day. What was the temperature at the end of the day?

Answer:

`T_2 = -22`

Explanation:

Given

Represent the initial temperature with T1

`T_1 = -6`

Represent the drop in temperature by D

`D = 16`

Required

Determine the new temperature (T2)

The question says that there was a drop of 16 degrees in temperature at the end of the day.

Using a number line, this means that we have to count 16 units to the left of -6.

This can be represented as:

`T_2 = T_1 - D`

`T_2 = -6-16`

`T_2 = -22`

Hence, the temperature at the end of the day is -22 degrees
