Three integers all less than 25 whose range is 11 and mean is 19

Sagot :

Answer:

13, 20 and 24.

Step-by-step explanation:

if the mean is 19 then x + y + z = 57

Range = 11 so we can write

y - x = 11

Adding to the first equation we have:

2y + z = 68

As each number is less than 25

y and z could be

24 and 20

and that would make x = 57 - (24 + 20) = 13

That fits in with the range being 11 ( as 24 - 13 = 11)

Answer is 13, 20 and 24.
