8 and 9
2,000/9 = 2222/9There are 222 of them.A simpler way to look at it is multiply 9 times a number and keep going up until the product is over 2000. (9 * 223) is 2007. One less (9 * 222) is 1998, so therefore there are 222 integers between 1 and 2000.
The LCD of 4/9 and 1/3 is 9. 4/9 - 3/9 = 1/9

The integers are 9 and 10.
Let's denote the two integers as x and y. We know that x + y = -9 and x - y = 5. By solving these two equations simultaneously, we can find that the two integers are -7 and -2. This is because -7 + (-2) = -9 and -7 - (-2) = 5.
The difference is the result. 9 - 7 = 2 The difference between 9 and 7 is 2.
The integers are 4 and 9, so the equation would be 16+81=? and 16+81=97
Two consecutive integers whose sum is 19 is 10 & 9; 10+9 = 19.
-2 + -3 + -4 = -9
That is the difference between 9 and 1.3, which is 7.7.
To find the sum of two integers with different signs, you simply combine them, and give the result the sign of the larger integer. For example, you have two integers: -9 and +5. You combine them, that is the +5 cancels out 5 of the -9, leaving -4.
All integers have factors. Some integers have some of the same factors as other integers. These are known as common factors. Since 9 and 12 both have 3 as a factor, 3 is a common factor of 9 and 12.
9 x 7 =63 pretty simple there
They are -10 and -9.
Let's call the smaller number n and the larger (n+9). Making the second statement into an equation: 5n = 3(n+9) + 7 5n = 3n + 27 + 7 5n = 3n + 34 2n = 34 n = 17 and n+9 = 26 Check: Do the number fit the problem? 5 * 17 = 7 + 3 * 26 85 = 7 + 78 TRUE, the numbers 17 and 26 are a valid solution for the problem.
The difference between two numbers is determined by subtracting the smaller number from the larger number. For example the difference between 12 and 9 is: 12-9=3. For negative integers, you will see that the difference is the total distance. For example, the difference between (-12) and 9 is 9-(-12) when you simplify by eliminating the double sign, the two minus signs become one plus sign: 9+12=21. More simply put, you will have to travel 12 to get from (-12) to zero, then another 9 to travel the total distance (difference) of 21.
