Responder:
Número total de bolas = 245/23
Explicación paso a paso:
Dado que:
Bolas blancas = 1/5
Bolas negras = 1/7
Bolas rojas = 7
Sea el número total de bolas = x
Bolas blancas = 1 / 5x
Bolas negras = 1 / 7x
Por tanto, total;
(x / 5 + x / 7 + 7) = x
((7x + 5x) / 35) +7 = x
(12x / 35) + 7 = x
7 = x - 12x / 35
7 = (35x - 12x) / 35
7 = 23 veces / 35
245 = 23x
x = 245/23

Answer: The instrument weigh 204 ounces on Earth.
Step-by-step explanation:
Since we have given that
Instrument weighed on the moon = 34 pounds
As we know that
The force of gravity on Earth is 6 times greater than on the moon.
So, the weight of instrument on the earth is 6 times the weight on the moon.
Mathematically, it is expressed as
Hence, the instrument weigh 204 ounces on Earth.
