Determine the distance between 6.5 and -7.2 on a number line. (1 point)
The distance between 6.5 and -7.2 on a number line is 13.7.
Subtract -6 - (-8)
To subtract -6 - (-8), first we need to rewrite the expression using the rule "minus a negative is the same as plus a positive." So, -6 - (-8) becomes -6 + 8.
Next, we can proceed with simple addition: -6 + 8 equals 2.
Therefore, -6 - (-8) is equal to 2.
17 - (-18)
To subtract 17 - (-18), we can apply the same rule as before: "minus a negative is the same as plus a positive." So, 17 - (-18) becomes 17 + 18.
Next, we can proceed with simple addition: 17 + 18 equals 35.
Therefore, 17 - (-18) is equal to 35.
To determine the distance between 6.5 and -7.2 on a number line, you can subtract the smaller number from the larger number. In this case, the larger number is 6.5 and the smaller number is -7.2.
6.5 - (-7.2) = 13.7
So, the distance between 6.5 and -7.2 on a number line is 13.7 units.
To determine the distance between two points on a number line, you can use the absolute value formula:
Distance = |Coordinates of Point A - Coordinates of Point B|
In this case, the coordinates of Point A are 6.5, and the coordinates of Point B are -7.2. So, we can plug these values into the formula:
Distance = |6.5 - (-7.2)|
First, simplify the subtraction inside the absolute value:
Distance = |6.5 + 7.2|
Next, add 6.5 and 7.2:
Distance = |13.7|
Finally, take the absolute value of 13.7:
Distance = 13.7
Therefore, the distance between 6.5 and -7.2 on a number line is 13.7 units.
