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.
First, locate -19 on the number line.
Then, count 12.1 spaces to the right.
The point where you stop counting will be the sum of -19 and 12.1 (p + q).
To find the sum p + q using a number line, follow these steps:
1. Draw a number line with a suitable scale. Label it with the numbers you will be working with, in this case, -19 and 12.1.
2. Locate the point -19 on the number line. Mark it with a dot or a small line.
3. Starting from the point -19, count 12.1 spaces to the right. You can use the scale of the number line to help you count accurately.
4. Mark the point where you end up after counting 12.1 spaces to the right. This point represents the sum p + q.
5. Read the number that corresponds to the marked point on the number line. This is the value of the expression p + q.
For example, if you end up at the point -6.9 after counting 12.1 spaces to the right from -19, then the sum p + q is -6.9.
