To find the sum p+q using a number line, follow these steps:
1. Start at the point 0 on the number line.
2. Since p is -19, move 19 units to the left on the number line. You will now be at the point -19.
3. Since q is 12.1, move 12.1 units to the right from -19. You will end up at the point -19 + 12.1 = -6.9.
4. The point where you end up, -6.9, represents the sum p+q on the number line.
To find the sum p + q using a number line, follow these steps:
1. Draw a number line. Start by labeling the line with integers in increments, such as -20, -19, -18, and so on. Make sure to have enough space to the right of -19 to accommodate the decimal value.
-20 -19 -18 -17 -16 -15 ...
2. Locate the starting point for p, which is -19 on the number line. Mark it with a dot or an "X" to indicate this position.
-20 -19(X) -18 -17 -16 -15 ...
3. Move to the right on the number line to represent the value of q. As q is 12.1, you need to move 12 units to the right and then reach the position of 0.1 by dividing the remaining distance into 10 equal parts.
-20 -19(X) -18 -17 -16 -15 ... 0.1
4. Count each unit while moving along the number line to find the sum of p + q. Start at -19 and count each unit until you reach 0.1.
-20 -19(X) -18 -17 -16 -15 ... 0.1
-19 -18 -17 -16 -15 ... 0.1
5. After counting, you will see that the sum of p + q is approximately -6.9.
To find the sum p+q using a number line, we can start with the first number, p = -19. Begin by finding -19 on the number line and marking it as the starting point.
Next, we need to add q = 12.1 to p = -19. To do this on the number line, we move 12.1 units to the right from the starting point of -19. Since q is positive, we move in the direction of increasing numbers.
To make it easier, you can break down 12.1 into two parts: 12 and 0.1. Start by adding 12 units to -19 on the number line. This will take you to -7. Now, we need to add the remaining 0.1 from the new starting point (-7).
To add 0.1, divide the distance between -7 and -6 into ten equal parts since there are ten intervals between -7 and -6 on the number line. Each part represents 0.1. Count one interval to the right from -7, and you will reach -6.9. This is where the additional 0.1 takes us.
Therefore, the sum p+q is -7 + 0.1, which equals -6.9. So, on the number line, the point representing the sum p+q is -6.9.
