this means find a number between 20 and 40 that when decreased by 25% is still a positive even number.
to decrease a number by 25% it must be divisible by 4. the first number before 40 that can be divided by 4 is 36 - 36/4=9 gives us 25% of 36, so to decrease 36 by 25% we ust subtract 9 from 36, 36-9=27 which is an odd number and therefore not a possible value for x. the next possible number before 36 is 32, 32/4=8, and 32-8=24 which is an even number and therefore a possible value for x.
it is also the only value for x is this example.
The sum of a positive integer and a negative integer is positive when the positive integer is greater. For example: 9 + (-5) = 4 In this case, the positive integer 9 is greater than the negative integer 5. Therefore, the sum is positive.
Not necessarily. That only applies if the positive integer is greater than the negative integer in absolute value.An integer.
Yes.
Yes.
As long as the negative integer is greater than the positive integer, a negative integer will result from addition, subtraction, multiplication, and division.
When the positive integer is greater than the negative integer.
It is an integer.
any positive integer
The sum of a positive integer and a negative integer is positive when the positive integer is greater. For example: 9 + (-5) = 4 In this case, the positive integer 9 is greater than the negative integer 5. Therefore, the sum is positive.
a positive integer
no
By definition, a negative integer is any integer less than zero. Similarly, a positive integer is any integer greater than zero. It should be immediately obvious that an integer cannot be both less than and greater than zero. Therefore, a negative integer cannot be greater than a positive integer.
Not necessarily. That only applies if the positive integer is greater than the negative integer in absolute value.An integer.
Any positive integer.
Yes.
Yes.
There is none, because there is always a greater integer.
