The distance is 15, because -6 is 6 spaces away from zero and 9 is 9 spaces away from zero. You add the two distances to find the distance between the two numbers.
To get the distance between ANY two points on a number line: * Subtract one number from the other * Take the absolute value of the result In symbols: distance(a, b) = | a - b |
Usually that sort of question wants to know where the square root lies. It is between 9 and 10.
In order to find the ratio of two areas, you times it by the number of a number to get the number of the numbers numbers number, and that number divide by the first number which is 6 and then do the square root of the numbers number to get that number, which you will times by 2.
See lemma 1.2 from the cut-the-knot link. Yes, you can.
By finding the difference of them
-6
The easiest way to find the distance between any two numbers on a number line is the bigger number minus the smaller. Here 23 - (-7) = 23+7 = 30. Remember that minus a negative number is the same as plus that number.
2 and -6
The distance is 15, because -6 is 6 spaces away from zero and 9 is 9 spaces away from zero. You add the two distances to find the distance between the two numbers.

There need not be any prime number between them.
Add the two numbers and divide by two, or find the number which is halfway between the two numbers.
It is proven that between two irrational numbers there's an irrational number. There's no method, you just know you can find the number.
There are no such numbers. Given any "next" number, it is possible to find one between 0.74 and that number. And then between 0.74 and THAT number and so on.
The distance to halfway from each of the numbers can be found by taking half the difference of the numbers: (70,458 - 21,639)/2 = 24,409.5, so the halfway number is 48,819 from either numbers. To find the actually halfway number, just add (or subtract) that distance:21,639 + 24,409.5 = 46048.570,458 - 24,409.5 = 46048.546,048.5 is halfway between 21,639 and 70,458.
There are infinitely many numbers between any two different numbers. To find a number exactly in the middle between two numbers, calculate the average. That is, add the two numbers, then divide the result by 2.
