Answer 1

во втором отрезе 7*2=14 м

в третьем отрезе 14-5=9 м

(7+14+9)=30м - всего ткани

4320/30=144р стоит 1 метр ткани

7*144=1008р - заплатили за первый отрез

14*144=2016р заплатили за второй отрез

9*144=1296р заплатили за третий отрез

Answer 2

Calculation of the Cost of Each Fabric Piece

To calculate the cost of each fabric piece, we need to determine the length of each piece. Let's break down the information provided:

- In the first piece, the length of the fabric is 7 meters. - In the second piece, the length of the fabric is twice that of the first piece. - In the third piece, the length of the fabric is 5 meters less than that of the second piece.

Let's calculate the length of each fabric piece:

1. First piece: 7 meters. 2. Second piece: twice the length of the first piece, which is 2 * 7 = 14 meters. 3. Third piece: 5 meters less than the length of the second piece, which is 14 - 5 = 9 meters.

Now that we have the lengths of each fabric piece, we can calculate the cost of each piece. The total cost for all three pieces is given as 4320 rubles.

To find the cost of each piece, we can divide the total cost by the total length of the fabric:

1. Calculate the total length of the fabric: 7 + 14 + 9 = 30 meters. 2. Divide the total cost by the total length: 4320 / 30 = 144 rubles per meter.

Therefore, the cost of each fabric piece is 144 rubles per meter.
