Question

Щенок тяжелее котёнка в 3 раза и тяжелее хомяка в 6 раз, а в месте они весят 1 кг 350 гр. Сколько весит каждый? Даю много балов

Answer 1

Хомяк - х кг,котёнок - 3х кг,щенок 6х кг
Х+3х+6х=1350
10х=1350
Х= 135 гр=0.135 кг - хомяк
0135*3=405гр=0,405 кг
135*6=810гр=0,81 кг

Answer 2

Calculating the Weights of the Animals

To solve this problem, we can set up a system of equations based on the given information. Let's denote the weight of the puppy as P, the weight of the kitten as K, and the weight of the hamster as H. We are given the following information:

1. The puppy is 3 times heavier than the kitten: P = 3K 2. The puppy is 6 times heavier than the hamster: P = 6H 3. Together, they weigh 1 kg 350 g: P + K + H = 1.35 kg

Solving the Equations

We can use the first two equations to express the weights of the kitten and the hamster in terms of the weight of the puppy:

From equation 1: K = P/3

From equation 2: H = P/6

Now, we can substitute these expressions into the third equation:

P + (P/3) + (P/6) = 1.35

Solving for P: P + (P/3) + (P/6) = 1.35 Multiply through by 6 to clear the fractions: 6P + 2P + P = 8.1 9P = 8.1 P = 0.9 kg

Now that we have the weight of the puppy, we can find the weights of the kitten and the hamster:

K = P/3 = 0.9/3 = 0.3 kg H = P/6 = 0.9/6 = 0.15 kg

Conclusion

So, based on the given information, the weights of the animals are: - The puppy weighs 0.9 kg - The kitten weighs 0.3 kg - The hamster weighs 0.15 kg
