4.9-16=. A:25 B:7 C:-25 D:-7
shtirl [24]

Answer and Step-by-step explanation:

It says your question is : 9-16=? And the answer for that would be -10. But that's not there in the options I think your question was supposed to be meant like this : 16-9=? cause then it would be 7 tho it's there in the options, the sign is wrong it's not -7 it's  +7 or just 7.

What is the solution to the equation k + 4 3/4 = 7?
Artemon [7]
Hi I don’t know if this is right but I got that k is equal to 4 I got that because if you do

4 times 3/4 you get 12/4 that is equal to 3.
Now you have k + 3=7 you move 3 to the other side and make it negative
K= 7-3
K=4

Hope this helped!

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.
