Describe how to find the sum p+q using a number line if p=−19 and q=12.1.
To find the sum p+q using a number line, follow these steps:
1. Start by locating 0 on the number line. This represents the starting point or reference point.
2. Move to the left on the number line to represent the negative value of p, which is -19. Place a marker on -19.
3. From -19, move to the right on the number line to represent the positive value of q, which is 12.1. Place a marker on 12.1.
4. Now, observe the location of both markers on the number line. The sum p+q is obtained by counting the distance between -19 and 12.1 on the number line.
5. To count the distance, you can start from either marker and count the number of units or steps required to reach the other marker. In this case, you would count the number of units from -19 to 0, which is 19 units, and then add the units from 0 to 12.1, which is 12.1 units.
6. Finally, add the units counted together: 19 + 12.1 = 31.1.
Therefore, the sum p+q is 31.1.

on a number line, then count
spaces to the right.
To find the sum p+q using a number line, follow these steps:
1. Start by locating 0 on the number line, which represents the starting point or reference point.
2. From 0, move to the left on the number line to represent the negative value of p, which is -19. Place a marker on -19.
3. From -19, count 19 spaces to the right on the number line, as indicated by the magnitude of p but in the opposite direction. Place a marker on the resulting number -0.1.
4. Now, from -0.1, move to the right on the number line to represent the positive value of q, which is 12.1. Count 12.1 spaces to the right from -0.1. You can break it down by counting 12 spaces to reach 11 and then count another 0.1 spaces to reach 12.1. Place a marker on the resulting number 12.1.
5. Observe the location of both markers on the number line. The sum p+q is represented by the number where the second marker is placed, which is 12.1.
Therefore, the sum p+q is 12.1.
To find the sum p+q using a number line when p is -19 and q is 12.1, follow these steps:
1. Draw a horizontal line to represent the number line.
2. Mark a point on the number line as the starting position.
3. Label this point as -19 to represent p.
4. Move to the right on the number line by 19 units to reach the point representing p.
5. Mark a new starting point at the current position.
6. Label this point as -19 + 12.1 to represent the sum of p and q.
7. Move to the right on the number line by 12.1 units to reach the point representing the sum of p and q.
8. Label this new point as -6.9.
9. The final labeled point (-6.9) represents the sum p+q on the number line.
Therefore, the sum of p+q is -6.9 based on the number line representation.
To find the sum p + q using a number line, you first need to understand how to represent positive and negative numbers on a number line.
1. Draw a horizontal line. This will be your number line.
2. Mark a point on the line to represent 0. This will serve as your reference point.
3. Now, let's represent the number p = -19 on the number line:
- Count 19 units to the left on the number line from the reference point.
- Mark a point at that location and label it as p.
4. Next, let's represent the number q = 12.1 on the number line:
- Count 12 units to the right on the number line from the reference point.
- Mark a point at that location and label it as q.
5. Calculate the sum by starting from p and moving towards q on the number line:
- Since p is negative, you need to move to the left.
- Move 19 units to the right from p.
- You will land on a point labeled as -6.9, which represents the sum p + q.
So, in this case, the sum -19 + 12.1 is equal to -6.9.
