The distance between 6.5 and -7.2 on a number line is 13.7.
Subtract −6−(−8).(1 point)
-6 - (-8) is equivalent to -6 + 8, which equals 2.
Subtract 17−(−18)
17 - (-18) is equivalent to 17 + 18, which equals 35.
To determine the distance between 6.5 and -7.2 on a number line, you can use the formula for finding the absolute value of the difference between two numbers.
The formula is: |a - b|
In this case, a = 6.5 and b = -7.2.
Therefore, the distance between 6.5 and -7.2 on a number line is |6.5 - (-7.2)|.
Simplifying the expression inside the absolute value, we have:
|6.5 + 7.2|
Adding 6.5 and 7.2, we get:
|13.7|
So, the distance between 6.5 and -7.2 is 13.7 units on a number line.
To determine the distance between two points on a number line, you need to find the absolute difference between the two points.
To find the absolute difference, subtract the smaller number from the larger number. In this case, you would subtract -7.2 from 6.5:
6.5 - (-7.2) = 6.5 + 7.2 = 13.7
The absolute difference between 6.5 and -7.2 is 13.7. Therefore, the distance between these two points on a number line is 13.7 units.
