Question

помогите решить - гусь тяжелее утки на 2кг., но легче щенка на 3кг. На сколько утка легче щенка?

Answer 1

Масса гуся = ?, но на 2 кг больше массы утки

Масса утки = ?

Масса щенка = ?, но на 3 кг больше массы гуся

Обозначим х кг - массу утки,тогда масса гуся = х + 2, а масса щенка = х + 3, тогда

3 + 2 = 5 (кг) - масса щенка больше массы утки.

Ответ: на 5 кг.
Если без х, то т.к мы знаем что гусь на 2 кг больше утки и на 3 кг меньше щенка, то разность веса щенка и утка равна сумме различий масы гуся от утки и щенка, 3+2=5 кг.
Ответ:5 кг 

Answer 2

Calculating the Weight Differences

To calculate how much lighter the duck is compared to the puppy, we can use the given information that the goose is 2kg heavier than the duck and 3kg lighter than the puppy.

Step 1: Calculate the weight of the duck. Step 2: Calculate the weight of the puppy. Step 3: Find the difference in weight between the duck and the puppy.

Step 1: Calculate the Weight of the Duck

The weight of the duck can be calculated by subtracting 2kg from the weight of the goose.

Step 2: Calculate the Weight of the Puppy

The weight of the puppy can be calculated by adding 3kg to the weight of the goose.

Step 3: Find the Difference in Weight Between the Duck and the Puppy

The difference in weight between the duck and the puppy can be calculated by subtracting the weight of the duck from the weight of the puppy.

Let's calculate the weights:

Weight of the Duck = Weight of the Goose - 2kg Weight of the Puppy = Weight of the Goose + 3kg Difference in Weight = Weight of the Puppy - Weight of the Duck

Calculations

Weight of the Duck = Goose's weight - 2kg Weight of the Puppy = Goose's weight + 3kg Difference in Weight = Weight of the Puppy - Weight of the Duck

Conclusion

The weight of the duck is 2kg less than the weight of the puppy.
