Answer 2

1)
Х+7х=864
8х=864
Х=864:8

Answer 3

Task Solution and Explanation

To solve the given problem, we need to find the amount of film in each roll, given that one roll has 7 times more film than the other, and the total amount of film in both rolls is 864 meters.

Let's start by drawing a diagram to represent the problem:

Let's represent the amount of film in the first roll as x meters.
Then, the amount of film in the second roll would be 7x meters.

Given that the total amount of film in both rolls is 864 meters, we can write the equation:
x + 7x = 864
8x = 864
x = 864 / 8
x = 108

So, the amount of film in the first roll is 108 meters, and in the second roll is 7 * 108 = 756 meters.

Answer

The amount of film in each roll is 108 meters and 756 meters respectively.
