Answer:
9, 11 and 19
Step-by-step explanation:
the first two integers I've picked are 19 and 9 because it gives a range of 10 and is less than 25
the range is the bigger number - smaller number
19 - 9 = 10
to find the third number we are given mean = 13
the third number = x
multiply both sides by 3 to get rid of the fraction
subtract both sides by 28
the third number is 11
the three integers are 9, 11 and 19
there are two other possible answers:
8, 13 and 18
7, 15 and 17
