w + 13 = 39
Subtract 13 from each side:
w = 26
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).
if the number is the same: 2x + 3x = 13 5x = 13 x= 13/5
Identify the number which, when increased by 13, equals 25. Thirteen more than a number is 25.
5
What number when doubled has seven added and gives 13?
Note that adding a negative number is equivalent to subtracting a positive number, so 13 + -8 is the same as 13 - 8 which equals 5.
The number 139 can be represented by various mathematical expressions. For example, it can be the sum of 100 and 39, or the product of 13 and 10 plus 9 (13 x 10 + 9). Additionally, it can also be expressed as an average, such as the average of 138 and 140.
273 13+8 = 21 and 13*21 = 273
The number is -13.
How about: 1 times 91 plus 4 = 95 or 7 times 13 plus 4 = 95
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
basically you asked what -28+21 which equals -7
