25X + 30 = 15X subtract 15X from each side 25X - 15X + 30 = 15X - 15X 10X + 30 = 0 subtract 30 from each side 10X + 30 - 30 = 0 - 30 10X = -30 divide both sides integers by 10 (10/10)X = - 30/10 X = - 3 ----------------check in original equation 25(- 3) + 30 = 15(- 3) - 75 + 30 = - 45 - 45 = - 45 ----------------checks

25 or 10 or 0.
Average = Sum/6 = 30
There are, of course, infinitely many solutions for this. For example, the average of any of the following pairs is equal to 10: 10 and 10 9 and 11 8 and 12 0 and 20 -10 and 30 9.9 and 10.1 9.8 and 10.2 etc.
10, just add them all together and divide by how many numbers there are. sometimes you will need a calculator but this time is a definite no
10% of 25 to the nearest hundred is 0.
