в 3 рулонах146,8м ткани,если в другом рулоне на18,4м больше чем в первом,а в третьем в двое больше,чемв первом.сколько метровткани было в каждом рулоне

Answer 1

Ответ:

Пошаговое объяснение:

х первый рулон

х+18.4 второй

2х третий

х+х+18.4+2х=146.8

4х+18.4=146.8

4х=128.4

х=32.1

х+18.4=50.5

2х=64.2

Answer 2

Let's assume the amount of fabric in the first roll is represented by "x" meters.

1. The second roll contains 18.4 meters more than the first roll, so its length is (x + 18.4) meters.
2. The third roll contains twice the length of the first roll, so its length is 2x meters.

The total length of fabric in the three rolls is 146.8 meters. So, we can set up the equation:

x + (x + 18.4) + 2x = 146.8

Now, let's solve for "x":

Combine the "x" terms:

4x + 18.4 = 146.8

Subtract 18.4 from both sides:

4x = 128.4

Divide by 4 to solve for "x":

x = 128.4 / 4 x = 32.1

Now that we have the value of "x," we can find the lengths of each roll:

First roll: x = 32.1 meters Second roll: x + 18.4 = 32.1 + 18.4 = 50.5 meters Third roll: 2x = 2 * 32.1 = 64.2 meters

So, there were 32.1 meters in the first roll, 50.5 meters in the second roll, and 64.2 meters in the third roll.
