The sum means that Eric is 3.3 m above sea level.
<h3>What is an addition expression?</h3>
This is a way of taking the sum of two or more expressions.
Given the following parameters
- The distance while descending = -13.7 meters
- The distance while ascending = +15.2 meters
An additional expression in the form of Descent + Ascent to represent this situation will be -13.7 + 15+ 2
<u>Calculate the sum:</u>
Sum = -13.7 + 15+ 2Sum = 3.3 meters
Hence the sum means that Eric is 3.3 m above sea level.

Answer:
The equation 7(-1 1/2) = -10 1/2 means that the temperature change from 3 a.m. to 10 a.m. was -10 1/2 degrees
Step-by-step explanation:
Initially, the temperature was 3 1/2 degrees Fahrenheit at 3 a.m. From 3 a.m., the temperature change at 1 1/2 degrees per hour for the next 7 hours. This means that the temperature change in the next 7 hours is:
Temperature change = 7(-1 1/2) = -10 1/2
In the next 7 hours from 3 a.m. to 10 a.m., that is at 10 a.m. (3 a.m. + 7 hours), the temperature change was -10 1/2 degrees Fahrenheit.
Hence:
The equation 7(-1 1/2) = -10 1/2 means that the temperature change from 3 a.m. to 10 a.m. was -10 1/2 degrees
