Escribe un número de tres cifras digamos a1b1c1, en el cual a1 sea distinto de c1; ahora invierte los dígitos a1 y c1, (obtendrá
Delicious77 [7]

Answer:

El número obtenido es:

  • <u>1089</u>.

Step-by-step explanation:

Vamos a escoger tres números sencillos para cada variable como:

  • a1 = 1
  • b1 = 2
  • c1 = 3

Por lo tanto, nuestro número de tres cifras es:

  • 123 (la única pauta es que a1 sea diferente a c1 y con este número la cumplimos)

Ahora, nos dice que invirtamos los números a1 y c1, por lo tanto, nuestro nuevo número de tres cifras sería:

  • 321

A continuación, nos menciona que restemos el menor del mayor, en este caso, nuestro número menor es 123 y el mayor es 321, por lo tanto:

  • 321 - 123 = <u>198</u> (Este resultado será el mismo sin importar cuáles números elijas para el ejercicio)

Como obtuvimos el número 198, se podría decir que:

  • a2 = 1
  • b2 = 9
  • c2 = 8

Ahora nos piden que invirtamos a2 y c2, por lo tanto nuestro nuevo número sería:

  • <u>891</u>

Y por último, nos solicita que sumemos los dos últimos números obtenidos, entonces tenemos:

  • 891 + 198 = <u>1089</u>

Por lo tanto, <u>el número obtenido al final es 1089</u>, el cual obtendrás sin importar qué número de tres cifras elijas al inicio, siempre y cuando no se repitan el primero y el tercer dígito.

What number is in between 6534 and 6565
ahrayia [7]

Answer:

I am assuming any number in between these two, so let's just say 6,550.

Step-by-step explanation:

If you count up from 6,534, you will eventually get to 6,550. If you continue to count up, you will eventually reach 6,565 which is bigger than 6,550.
