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 marking -19 on the number line. Since p is equal to -19, this will be your starting point.
Next, count 12.1 spaces to the right on the number line. This means you move 12.1 units towards the right from the -19 mark.
At the end of the 12.1 spaces, you will reach the point that represents the sum p+q. This point on the number line will give you the value of the sum p+q.
To find the sum of p+q using a number line, follow these steps:
1. Begin by finding the point on the number line that represents the value of p. In this case, p is equal to -19. So, locate the point -19 on the number line.
2. Once you have located -19 on the number line, you need to find the value of q. In this scenario, q is equal to 12.1. So, visualize or locate the point 12.1 on the number line.
3. Now, count the spaces on the number line moving to the right from the point representing p (-19) towards the point representing q (12.1). Each space on the number line corresponds to an increment of 1.
4. Count the number of spaces between the two points. In this case, you would count 31.1 spaces.
5. The sum of p+q is equal to the number of spaces counted. Thus, the sum of -19 + 12.1 is equal to 31.1.
Therefore, the answer is 31.1.
To find the sum of p and q using a number line, follow these steps:
1. Start by plotting the point -19 on the number line. In this case, p = -19, so you would mark -19 on the number line.
2. Now, count 12.1 spaces to the right from -19. Each space represents a whole number on the number line.
3. If you encounter a decimal number like 12.1, you can think of it as counting in tenths. So, to count 12.1 spaces, move 12 whole numbers to the right on the number line, and then move an additional 1 tenth of a space.
4. After counting 12.1 spaces, you will land on a new point. This new point represents the sum of p and q.
5. To determine the sum mathematically, you can add p and q together. In this case, sum = -19 + 12.1 = -6.9.
So, using a number line, you would plot -19 and then count 12.1 spaces to the right to find the sum of p and q, which in this case is -6.9.
