The rainfall in a town was 2.3 inches above normal in June. In July, the rainfall was 1.2 inches below normal. What was the difference in rainfall between the months?(1 point)
The difference in rainfall between the months is 2.3 - (-1.2) = 3.5 inches.
A submarine was at a depth of 106.3 feet below sea level. After 5 hours, the submarine was at 481.2 feet below sea level. How far did the submarine travel?(1 point)
The submarine traveled a distance of 481.2 - 106.3 = 374.9 feet.
The water level of a river is below normal levels. Its water level is at 1 1/2
meters below sea level. During the summer, the river drops another 2 1/3
meters below sea level. What is the water level at the end of summer? Remember, the elevation is below sea level.Account for this in your answer
To find the water level at the end of summer, we need to calculate the sum of the initial water level and the drop during the summer.
The initial water level is 1 1/2 meters below sea level, which can also be expressed as -1 1/2 meters.
The drop during the summer is 2 1/3 meters below sea level, which can also be expressed as -2 1/3 meters.
To find the sum, we need to add -1 1/2 meters to -2 1/3 meters:
-1 1/2 meters + (-2 1/3 meters)
First, we need to convert the mixed numbers to improper fractions:
-1 1/2 meters = -3/2 meters
-2 1/3 meters = -7/3 meters
Now, we can add the fractions:
-3/2 meters + (-7/3 meters)
To add fractions, we need to have a common denominator. In this case, the common denominator is 6:
(-3/2 meters)(3/3) + (-7/3 meters)(2/2)
= (-9/6 meters) + (-14/6 meters)
Now we can add the fractions:
= (-9/6 - 14/6) meters
= -23/6 meters
Finally, we can write the water level at the end of summer as a mixed number:
-23/6 meters = -3 5/6 meters below sea level
Therefore, the water level at the end of summer is 3 5/6 meters below sea level.

To find the difference in rainfall between the months of June and July, we need to subtract the rainfall in July from the rainfall in June.
Given that the rainfall in June was 2.3 inches above normal, we can represent it as +2.3 inches. The rainfall in July was 1.2 inches below normal, which we can represent as -1.2 inches.
To find the difference, we subtract -1.2 inches from +2.3 inches:
(+2.3) - (-1.2) = +2.3 + 1.2
This simplifies to:
2.3 + 1.2 = 3.5
Therefore, the difference in rainfall between June and July is 3.5 inches.
