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, start by representing the number -19, which is the value of p. Mark a point on the number line corresponding to -19.
Next, locate the number 12.1, which is the value of q, on the number line and mark another point.
To find the sum p+q, count the number of spaces between the two marked points on the number line. The distance between the points represents the sum p+q.
Therefore, to find the sum p+q using a number line given that p=-19 and q=12.1, you need to mark the points -19 and 12.1 on the number line, and then count the number of spaces between these points to determine the sum.
To find the sum p+q using a number line, follow these steps:
1. Draw a number line and label it with the negative and positive numbers, starting from zero.
-19 -18 -17 ... 0 ... 11 12 13 14 15 16 17 18 19
2. Locate the position of the point -19 on the number line by going 19 spaces to the left of zero.
3. Starting from the point -19, count 12.1 spaces to the right.
-19 -18 -17 ... 0 ... 11 12 12.1 13 14 15 16 17 18 19
4. The point where you end up after counting 12.1 spaces to the right is the sum p+q.
Therefore, p+q = 12.1.
