Question

По первой накладной со склада было выдано 0,7 имевшегося кирпича, а по второй - 0,4 остатка, после чего кирпича на складе осталось 5850 штук. какое количество кирпича было на складе первоначально? по порядку действия

Answer 1

На складе было х штук кирписа
выдано по первой накладной 0,7х
выдано по второй накладной 0,4(х-0,7х)
составляем уравнение
х-0,7х-0,4(х-0,7х)=5850
х-0,7х-0,4х+0,7х=5850
х-0,4х=5850
0,6х=5850
х=5850:0,6
х=9750 штук кирпича было на складе

Calculation of the Initial Quantity of Bricks on the Warehouse

To determine the initial quantity of bricks on the warehouse, we can use the information provided in the question. Let's break down the steps to solve the problem:

1. From the first invoice, 0.7 of the available bricks were issued from the warehouse. 2. From the second invoice, 0.4 of the remaining bricks were issued from the warehouse. 3. After these transactions, there were 5850 bricks left on the warehouse.

To find the initial quantity of bricks, we need to work backward from the remaining quantity. Let's calculate it step by step:

1. Calculate the quantity of bricks issued from the warehouse based on the second invoice: - Remaining quantity after the first invoice: 0.7 * Initial quantity - Quantity issued from the warehouse based on the second invoice: 0.4 * (0.7 * Initial quantity)

2. Subtract the quantity issued from the warehouse based on the second invoice from the remaining quantity to find the quantity of bricks before the second invoice: - Remaining quantity - Quantity issued from the warehouse based on the second invoice = Quantity of bricks before the second invoice

3. Calculate the initial quantity of bricks based on the remaining quantity after the second invoice: - Quantity of bricks before the second invoice + Remaining quantity after the second invoice = Initial quantity of bricks

Let's apply these calculations:

1. Calculate the quantity of bricks issued from the warehouse based on the second invoice: - Quantity issued from the warehouse based on the second invoice = 0.4 * (0.7 * Initial quantity) = 0.28 * Initial quantity

2. Subtract the quantity issued from the warehouse based on the second invoice from the remaining quantity to find the quantity of bricks before the second invoice: - Remaining quantity - Quantity issued from the warehouse based on the second invoice = 5850 - 0.28 * Initial quantity

3. Calculate the initial quantity of bricks based on the remaining quantity after the second invoice: - Quantity of bricks before the second invoice + Remaining quantity after the second invoice = Initial quantity of bricks - (5850 - 0.28 * Initial quantity) + 0.28 * Initial quantity = Initial quantity of bricks

Now, we can solve this equation to find the initial quantity of bricks.
