Yes, all negative whole numbers, including -13, are integers.
-13 is rational and an integer.
No - an integer is a whole number - the closest integers to 12.5 are 12 and 13.
13.
13 is an integer and so the answer is 13 months, or k*13/k moths where k is any non-zero integer. There is nothing in the question requiring the measurement unit to be changed and, in any case, the answer would depend on whether the unspecified unit was a week or a year (or something else).
The positive integer factors of 273 are:1, 3, 7, 13, 21, 39, 91, 2731,3 7,13,21,39,91,273
-13 is an integer.
-13 is already an integer. It corresponds to the absolute value 13.
Integer.
13
-13 is rational and an integer.
-13/100
No, it is an integer.
To find the integer represented by 13 positive tiles and 26 negative tiles, you can subtract the number of negative tiles from the number of positive tiles. This calculation is (13 - 26), which equals (-13). Therefore, the integer represented is (-13).
2x + 1 is equal to or less than 13.
To the nearest integer, 13
-3
-7(13) = -91 is an integer, not a fraction!
