Which letter on the number line represents the result of added to ?

The number line showing numbers from -10 to 10 is each divided into 5 segments in increments of 5, has point A one segment to the right of -10, point B is four segments to the right of -5, point C is one segment to the right of 0 and point D is four segments to the right of 5.

To determine which letter on the number line represents the result of adding two points together, we first need to identify the values of points A, B, C, and D based on their described positions:

  1. Point A: One segment to the right of -10 is -10 + 5 = -5.
  2. Point B: Four segments to the right of -5 is -5 + (4 * 5) = -5 + 20 = 15, but since the line goes only from -10 to 10, this point does not fall on the number line segment.
  3. Point C: One segment to the right of 0 is 0 + 5 = 5.
  4. Point D: Four segments to the right of 5 is 5 + (4 * 5) = 5 + 20 = 25, but again, this point exceeds the visible number line.

Thus, it looks like A (-5) and C (5) are the only relevant points since Point B and D exceed the -10 to 10 range.

If we need to find the result of adding point A and point C:

  • Point A: -5
  • Point C: 5

Calculating the addition:

-5 + 5 = 0.

The result 0 is exactly on the number line, located at point C.

Thus, the answer is C, as it represents the value 0 on the number line.
