Question

2.В мастерской было 2 куска материи длинной 96м и 84м. Из них сшили плащи. Из второго куска получили на 3 плаща меньше. Чем из первого. Сколько плащей сшито из каждого куска? Можно с краткой записью пж(;´༎ຶٹ༎ຶ`)

Answer 1

Пошаговое объяснение:

Пусть из второго куска сшито х плащей.       ⇒

Из первого куска сшито (х+3) плаща.

$\frac{96}{x+3}=\frac{84}{x}\\ 96x=84*(x+3)\\ 96x=84x+252\\ 12x=252\ |:12\\ x=21.\\ 21+3=24.$

Ответ: из первого куска сшито 24 плаща,

            из второго куска сшито 21 плащ.

Answer 2

Solution:

Let's solve this step by step.

1. Calculate the number of coats from the first piece of fabric: - Length of the first piece of fabric = 96m - Assuming the length required for one coat is 4m, the number of coats that can be made from the first piece of fabric is 96m / 4m = 24 coats.

2. Calculate the number of coats from the second piece of fabric: - Length of the second piece of fabric = 84m - Since the second piece of fabric yields 3 fewer coats than the first piece, the number of coats from the second piece is 24 - 3 = 21 coats.

3. Summary: - From the first piece of fabric, 24 coats can be made. - From the second piece of fabric, 21 coats can be made.

So, the number of coats that can be made from each piece of fabric is 24 and 21, respectively.
