Describe how to find the sum p+q using a number line if p=−19 and q=12.1.(1 point)
First find
on a number line, then count
spaces to the right.
To find the sum p+q using a number line, we start with the given value of p=−19. On a number line, we locate the number -19.
Next, we need to add q=12.1 to -19. We count 12 spaces to the right from -19 on the number line.
By counting 12 spaces to the right from -19, we reach the point 12.1 on the number line.
Thus, the sum p+q is equal to -19 + 12.1 which equals -6.9.
To find the sum p+q using a number line, follow these steps:
1. Start by placing a point on the number line to represent the number p, which is -19. You can label this point as -19.
2. Next, locate the number q on the number line. In this case, q is 12.1. Since 12.1 is positive, go to the right of the number line.
3. Count 12 spaces to the right starting from the point representing -19. Each space represents one unit on the number line. Label this point as 12.1.
4. Finally, add the two labeled points on the number line together. The sum of -19 and 12.1 is -6.9.
