Допоможіть. Максим купив 2 літачки по 20 грн кожний та 2 машинки. Вартість машинок у 5 разів менше
за вартість літачків. Скільки коштує машинка? Печиво розклали у 8 коробок по 5 кг у кожну, а зефір-у коробки по 4 кг в кожну. Коробки із зефіром важать у 2 рази меньше, ніж коробки з печевом. Скільки коробок знадобилося, щоб розкласти зефір?

Ответы на вопрос

1) 20*2=40 грн за оба самолётика (или что это там было) :)
40/5=8 грн стоят две машинки
8/2= 4 грн за одну машинку.
2) 8*5=(4*x)*2;
4x=20;
x=20/4;
x=5 коробок.



Calculation of the Cost of the Toy Car
To find the cost of the toy car, we need to determine the price of one toy car. We are given that Maxim bought 2 airplanes for 20 UAH each and 2 toy cars. The cost of the toy cars is 5 times less than the cost of the airplanes.
Let's calculate the cost of one airplane first. Since Maxim bought 2 airplanes for a total of 40 UAH, the cost of one airplane is 40 UAH / 2 = 20 UAH.
Now, we can calculate the cost of one toy car. We know that the cost of the toy cars is 5 times less than the cost of the airplanes. Therefore, the cost of one toy car is 20 UAH / 5 = 4 UAH.
So, the toy car costs 4 UAH.
Calculation of the Number of Boxes for Marshmallows
To determine the number of boxes needed to distribute the marshmallows, we need to compare the weight of the marshmallow boxes to the weight of the cookie boxes. We are given that the cookie boxes weigh twice as much as the marshmallow boxes.
Let's assume the weight of one marshmallow box is x kg. Therefore, the weight of one cookie box is 2x kg.
We are also given that there are 8 boxes of cookies, each weighing 5 kg, and the same number of boxes of marshmallows, each weighing 4 kg.
To find the value of x, we can set up an equation:
8 * 5 kg = x * 4 kg
Simplifying the equation:
40 kg = 4x kg
Dividing both sides of the equation by 4:
10 kg = x kg
Therefore, the weight of one marshmallow box is 10 kg.
Since each marshmallow box weighs 10 kg, and the total weight of the marshmallows is not given, we cannot determine the exact number of boxes needed to distribute the marshmallows.
Please provide the total weight of the marshmallows so that we can calculate the number of boxes needed.
