Проволоки; 1д=Х; 2д=2*Х; 3д=3Х; по условию 3*Х-Х=30кг; 2Х=30кг; Х=30:2=15кг; 3Х=3*15=45кг; всего Х+2х+3х=15+30+45=90кг; Ответ: всего за три дня 90кг проволоки выдали. _____________________________ можно частями решить; 1д=1ч; 2д=2ч; 3д=3ч; 3ч-1ч=30кг; 2ч=30кг; 1ч=30:2=15кг; 3ч=3*15=45кг; 30+45+15=90кг всего

Answer 2

Calculation of Wire Issued in Three Days

To calculate the total amount of wire issued in the three days, we need to consider the amounts issued on each day and the given ratios.

Let's assign variables to represent the amounts of wire issued on each day: - First day: x kg - Second day: 2x kg (twice as much as the first day) - Third day: 3x kg (three times as much as the first day)

We also know that the amount issued on the first day is 30 kg less than the amount issued on the third day.

Therefore, we can set up the following equation: x = 3x - 30

Solving this equation will give us the value of x, which represents the amount of wire issued on the first day.

Let's solve the equation:

x = 3x - 30 30 = 2x x = 15

Now that we have the value of x, we can calculate the amounts of wire issued on each day: - First day: 15 kg - Second day: 2 * 15 = 30 kg - Third day: 3 * 15 = 45 kg

To find the total amount of wire issued in the three days, we add up the amounts: 15 + 30 + 45 = 90 kg

Therefore, a total of 90 kg of wire was issued in these three days.
