To find the distance from the basement floor at -16 feet to the roof at 37 feet, we need to calculate the difference in elevation between these two points.
The elevation of the basement floor is -16 feet, and the elevation of the roof is 37 feet. The distance can be determined by subtracting the basement elevation from the roof elevation:
\[
\text{Distance} = \text{Roof Elevation} - \text{Basement Elevation}
\]
\[
\text{Distance} = 37 - (-16)
\]
\[
\text{Distance} = 37 + 16
\]
\[
\text{Distance} = 53 \text{ feet}
\]
Thus, the distance from the basement floor to the roof is **53 feet**.
The correct response is:
53
The elevation of the basement floor is -16 feet, and the elevation of the roof is 37 feet. The distance can be determined by subtracting the basement elevation from the roof elevation:
\[
\text{Distance} = \text{Roof Elevation} - \text{Basement Elevation}
\]
\[
\text{Distance} = 37 - (-16)
\]
\[
\text{Distance} = 37 + 16
\]
\[
\text{Distance} = 53 \text{ feet}
\]
Thus, the distance from the basement floor to the roof is **53 feet**.
The correct response is:

To simplify the expression \(-8.5 - (-3.7)\), we first need to recognize that subtracting a negative number is equivalent to adding the positive version of that number:
\[
-8.5 - (-3.7) = -8.5 + 3.7
\]
Now, we perform the addition:
\[
-8.5 + 3.7
\]
If we think of it on a number line, moving 3.7 units to the right from -8.5:
1. The first step is to find the total:
\[
-8.5 + 3.7 = -4.8
\]
Thus, the simplified expression is:
\(-4.8\)
The correct response is:
-4.8
\[
-8.5 - (-3.7) = -8.5 + 3.7
\]
Now, we perform the addition:
\[
-8.5 + 3.7
\]

To simplify the expression \(25 - (-80)\), we recognize that subtracting a negative number is equivalent to adding the positive version of that number:
\[
25 - (-80) = 25 + 80
\]
Now, we can perform the addition:
\[
25 + 80 = 105
\]
Thus, the simplified expression is:
**105**
The correct response is:
105
\[
25 - (-80) = 25 + 80
\]
Now, we can perform the addition:
\[
25 + 80 = 105
\]
Thus, the simplified expression is:
**105**
The correct response is:
105

To simplify the expression \(-18.5 - 17.5\), we can combine the two negative numbers:
\[
-18.5 - 17.5 = -(18.5 + 17.5)
\]
Now we can add the two values:
\[
18.5 + 17.5 = 36
\]
Therefore, we have:
\[
-18.5 - 17.5 = -36
\]
Thus, the simplified expression is:
\(-36\)
The correct response is:
-36
\[
-18.5 - 17.5 = -(18.5 + 17.5)
\]
Now we can add the two values:
\[
18.5 + 17.5 = 36
\]
Therefore, we have:
\[
-18.5 - 17.5 = -36
\]
Thus, the simplified expression is:
\(-36\)
The correct response is:
-36
