Answer:
|x - 3.5| = 0.8
4.3 and 2.7
Explanation:
The distance between points a and b on the number line is |a - b|.
If you write |a - b| = 5, then the distance between points a and b is 5.
We are looking for two points whose distance from 3.5 is 0.8.
We don't know what the two points are, so we use the variable x for the points.
The distance from x to 3.5 is |x - 3.5|.
The distance is 0.8, so |x - 3.5| must equal 0.8.
Answer: |x - 3.5| = 0.8
Solve the equation for x.
x - 3.5 = 0.8 or x - 3.5 = -0.8
x = 4.3 or x = 2.7
Answer: 4.3 and 2.7
