-15 + x = 21
Add 15 to each side of the equation:
x = 36
The result will be positive in this case.

90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.
When 3 is added 5 times to a number the result is 15 if the number is 0, otherwise this is not true. However, the amount added to the number is always 15. Let's say the variable x is our number and y is the result, then x+3+3+3+3+3=y. You can add all the 3's together now. So you have x+15=y. Now if the starting number is 0, you have 15=y, so the result is 15.
15 is an integer, not a fraction. If you must, you can express it as a fraction as 15/1.Multiply the numerator (top) and the denominator (bottom) of this fraction by any non-zero integer. You will have an equivalent fraction.15 is an integer, not a fraction.

The original integer's value is increased by one - (15 + 1 = 16).
The result will be positive in this case.
No, 15 is not a factor of 5. In mathematics, a factor of a number is an integer that can be multiplied by another integer to produce the original number. In this case, 15 cannot be multiplied by any integer to result in 5, making it not a factor of 5.
It is: -2 because -2-15 = -10-7 => -17 = -17

90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.
To solve this set it up as an equation. Say x = some integer, so x + 15 = 10 times -3. x + 15 = -30, so x = -30 - 15 which means x = -45
15/3 = 5 5 is an integer.
When 3 is added 5 times to a number the result is 15 if the number is 0, otherwise this is not true. However, the amount added to the number is always 15. Let's say the variable x is our number and y is the result, then x+3+3+3+3+3=y. You can add all the 3's together now. So you have x+15=y. Now if the starting number is 0, you have 15=y, so the result is 15.
It is divisibility by 3 and divisibility by 5.Divisibility by 3: the digital root of an integer is obtained by adding together all the digits in the integer, with the process repeated if required. If the final result is 3, 6 or 9, then the integer is divisible by 3.Divisibility by 5: the integer ends in 0 or 5.
An integer is a number, positive or negative. So 15 is an integer.
