Question

в аквариуме морского музея 444 моллюска. из них гребешков в 5 раз больше ,чем мидий ,а жемчужниц столько сколько ,сколько мидий и гребешков вместе. определите число моллюсков каждого вида

Answer 1

Пусть  -  х мидий, тогда - 5х гребешков , а  - х+5х  жемчужин 
Уравнение:
х+5х+5х+х=444 
12х=444
х=37  - мидий
2)5•37=185 - гребешков
3)185+37=222 -жемчужин

Ответ:   37, 185, 222 .

 

 

Answer 2

Обозначим мидии через х, тогда гребешков будет 5х, а жемчужниц ( х+5х )

Составляем уравнение:

х + 5х + ( х+5х ) = 444

12х = 444

х = 37 - всего мидий

Следовательно гребешков 

5*37 = 185 - гребешков

А жемчужниц:

37+185 = 222 - всего жемчужниц

Проверка: 37+185+222 = 444

Answer 3

Calculation of the Number of Mollusks in the Aquarium

To determine the number of mollusks of each species in the aquarium, we need to consider the given information:

- The number of scallops is 5 times greater than the number of mussels. - The number of pearl oysters is equal to the combined number of mussels and scallops.

Let's assign variables to represent the number of mollusks for each species:

- Let x be the number of mussels. - Then, the number of scallops is 5x. - The number of pearl oysters is x + 5x = 6x.

To find the value of x, we need additional information or assumptions about the total number of mollusks in the aquarium. Unfortunately, the given information does not provide any clues about the total number of mollusks.

Without knowing the total number of mollusks, we cannot determine the exact number of mollusks for each species in the aquarium.

If you have any additional information or assumptions, please provide them so that we can calculate the number of mollusks accurately.
