Answer 1

9514 1404 393

Answer:

  26, 37, 40, 48

Step-by-step explanation:

Whole numbers between 20 and 50 will have 10s digits in the range 2–5.

When 4 is added to these numbers, we get ...

  2+4 = 6

  3+4 = 7

  4+4 = 8

  5+4 = 9

When 4 is subtracted from these numbers, we get ...

  2-4 = -2

  3 -4 = -1

  4 -4 = 0

  5 -4 = 1

__

The numbers we can make using the given 10s digits and their corresponding 1s digit(s) are ...

  26, 37, 40, 48

__

We note that any number with a 10s digit of 5 and a 1s digit other than 0 will be out of range.
