Answer:
Cada hermana debe pagar $900.
A las dos hermanas que pagaron $1,200 se les reembolsarán $300.
Step-by-step explanation:
Dado que el costo mensual del servicio de internet cuesta $300 por mes, y que el mismo fue contratado por 9 meses por 3 hermanas que se comprometieron a pagarlo en partes iguales, el costo total del servicio será de $2,700 (300 x 9), y cada hermana deberá pagar $900 (2,700 / 3).
Así, si dos de las hermanas pagaron $1,200 cada una, la tercer hermana les deberá reembolsar $300 a cada una de ellas (1,200 - 300).
Answer:
<em>x=4</em>
Step-by-step explanation:
Simplifying
4x + 16 + -1x = 22 + 6
Reorder the terms:
16 + 4x + -1x = 22 + 6
Combine like terms: 4x + -1x = 3x
16 + 3x = 22 + 6
Combine like terms: 22 + 6 = 28
16 + 3x = 28
Solving
16 + 3x = 28
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-16' to each side of the equation.
16 + -16 + 3x = 28 + -16
Combine like terms: 16 + -16 = 0
0 + 3x = 28 + -16
3x = 28 + -16
Combine like terms: 28 + -16 = 12
3x = 12
Divide each side by '3'.
x = 4
Simplifying
x = 4
Hope this helps! And please correct me if I'm wrong so others can have the correct answer.
