Se escribe una equacion y se resolve.
Vamos a usar x para representar el peso de la piedra.
En en platillo que tiene la piedra, el peso total es: x + 1/9 + 2/3
En el otro platillo: 1/2 + 1/3
La balanza esta equilibrada por eso los pesos en los platillos son iguales.
x + 1/9 + 2/3 = 1/2 + 1/3
x + 2/18 + 12/18 = 9/18 + 6/18
x + 14/18 = 15/18
x = 1/18
Respuesta: La piedra pesa un octavo de kilogramo.
Answer:
1520
Step-by-step explanation:
Pela pergunta acima, sabemos que:
1 parcela mensal = 304
5 parcelas mensais = x
Multiplicação cruzada
x = 5 prestações mensais × 304/1 prestações mensais
= 1520
Portanto, o valor que ele pagou pelo dispositivo é 1520
