Question

Реши задачу ,составляя уравнение.В мастерской получили заказ сшить 306 костюмов.В первый день в мастерской сшили 26 костюмов,в оставшиеся дни по 28 костюмов в день.За сколько дней в мастерской выполняли заказ?

Answer 1

26+28*х=306
28*х=306-26
28*х=280
х=280/28
х=10
В первый день 26 костюмов, а в оставшиеся 10 по 28 костюмов. Итого 11 дней

Answer 2

Problem Analysis

To solve this problem, we need to determine the number of days it took to complete the order of 306 costumes. On the first day, 26 costumes were sewn, and on the remaining days, 28 costumes were sewn each day. We can set up an equation to represent this situation.

Mathematical Equation

Let's assume that it took x days to complete the order. The equation can be written as follows:

26 + 28(x - 1) = 306

Solving the Equation

To find the value of x, we can solve the equation:

26 + 28(x - 1) = 306

Let's simplify the equation:

26 + 28x - 28 = 306

Combine like terms:

28x - 2 = 306

Add 2 to both sides:

28x = 308

Divide both sides by 28:

x = 11

Answer

It took 11 days to complete the order of 306 costumes in the workshop.

Note: The solution to the equation is based on the assumption that the number of costumes sewn each day remains constant.
