Question

8. The sum of three consecutive odd numbers
is 57. What are the three numbers?

Answer 1

Respuesta:

the 3 numbers are 18, 19 and 20 respectively

Explicación paso a paso:

the following expression arises

x + x + 1 + x+ 2 = 57

3x + 3 = 57

3x = 57 - 3

3x = 54

x = 54/3

x = 18

x = 18

x+1 = 18+1 = 19

x+2 = 18+2 = 20
