Just subtract the lowest number from the greatest number. For example, the distance between 3 and 8, is 8 - 3 = 5 units, the distance between -2 and 3, is 3 - (-2) = 3 + 2 = 5 units, the distance between -4 and -2, is -2 - (-4) = -2 + 4 = 2 units.
-4.25 on a number line is to the left of 0 but to the right of -5. It's like being stuck between a rock and a hard place, but in math terms. So basically, it's just a fancy way of saying it's a negative number that's a smidge more than -4.
The square root of 29 is an irrational number, close to (but not equal to) 5.385; on a number line, this is a point between 5 and 6 closer to 5 than 6. The number can also be represented as a continued fraction. You can find a link to an image of this representation below.
If you mean the perpendicular distance from the coordinate of (7, 5) to the straight line 3x+4y-16 = 0 then it works out as 5 units.
(3-1)2 + (5-8)2 = 13 and the square root of this is the distance between the points

Yes, the distance between -5 and 3 on a number line is 8. (The distance from -5 to zero is 5, which is the absolute value).

A number's distance from 0 on a number line is called absolute value. The absolute value of 5 is 5 and the absolute value of -5 is also 5.
The distance between 1 and .5 is (1 - .5)/2 which is .25. Add that to .5 to get the number halfway between the points: .5 + .25 = .75.So the point halfway between is .75 or 3/4.
Just subtract the lowest number from the greatest number. For example, the distance between 3 and 8, is 8 - 3 = 5 units, the distance between -2 and 3, is 3 - (-2) = 3 + 2 = 5 units, the distance between -4 and -2, is -2 - (-4) = -2 + 4 = 2 units.
5
There is no number between 5 and 5. It is the same point on the number line and a word like between would imply a space from one point to the next on the number line.
At the number 2, draw a vertical line (perpendicular to the number line) and mark a distance of 1 unit on this line. Call this point X The distance from 0 to X is sqrt(5). Put a compass with its point at 0 and the pencil at X, and then draw an arc to cut the number line. That will be sqrt(5) on the number line.
The distance between Bangalore and Bucharest is 5 700 km (straight line).
The absolute value of a number is its distance from zero on a number line. |a| means the absolute value of a. Basically, |5| = |-5| = 5; |x| = |-x| = x, etc.
45 is nearest to 50 because it is closer to 50 on the number line. When determining which number is closer, you can look at the distance between the numbers. In this case, the distance between 45 and 50 is 5, while the distance between 45 and 40 is 5 as well. Since 5 is smaller than 10, 45 is closer to 50 than it is to 40.
