I want to compare the distances of two different stores from home. What key word shows that you are finding the difference between rational numbers?
To find the balance in Mark's account after the bank fee, we need to subtract the fee amount from the initial balance.
Initial balance = −$11
Fee charged by the bank = $25
To find the balance, we subtract the fee from the initial balance:
Balance = Initial balance - Fee
Balance = −$11 - $25
Subtracting a positive amount is the same as adding a negative amount, so we can rewrite the equation as:
Balance = −$11 + (−$25)
Adding the negative numbers:
Balance = −$36
Therefore, the balance in Mark's account after the bank fee is −$36.
To determine the water level at the end of summer, we need to add the additional drop in the river to its initial level below sea level.
Initial water level below sea level = 112 meters
Additional drop during summer = 213 meters
To find the water level at the end of summer, we add the additional drop to the initial level:
Water level at the end of summer = Initial water level + Additional drop
Water level at the end of summer = (−112 meters) + (−213 meters)
Adding negative numbers:
Water level at the end of summer = −112 meters − 213 meters
Water level at the end of summer = −325 meters
Therefore, at the end of summer, the water level of the river is 325 meters below sea level.
To calculate the distance the submarine traveled, we need to find the difference between its initial depth and its final depth.
Initial depth = 106.3 feet below sea level
Final depth = 481.2 feet below sea level
To find the distance traveled, we subtract the initial depth from the final depth:
Distance traveled = Final depth - Initial depth
Distance traveled = 481.2 feet - 106.3 feet
Subtracting the depths, we have:
Distance traveled = 374.9 feet
Therefore, the submarine traveled a distance of 374.9 feet.
Yes, 0.3 can be expressed as the fraction 3/10.
The situation that describes opposite quantities that, when combined, would equal 0 is: "A deposit of $10 to a bank, a fee charged of $20, and a deposit of $30."
The key word that shows finding the difference between rational numbers is "compare."
Mark had a balance of −$11
in his checking account. The bank charged a $25 fee. What is the balance in the account?
The water level of a river is below normal levels. Its water level is at 112
meters below sea level. During the summer, the river drops another 213
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.(1 point)
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?
To find the difference in rainfall between June and July, we need to subtract the rainfall in July from the rainfall in June.
June rainfall above normal = 2.3 inches
July rainfall below normal = 1.2 inches
To find the difference in rainfall, we subtract the July rainfall from the June rainfall:
Difference in rainfall = June rainfall - July rainfall
Difference in rainfall = 2.3 inches - (-1.2 inches)
Subtracting a negative is the same as adding a positive, so we can rewrite the equation as:
Difference in rainfall = 2.3 inches + 1.2 inches
Adding the positive numbers:
Difference in rainfall = 3.5 inches
Therefore, the difference in rainfall between June and July is 3.5 inches.
