Answer 1

The total length of the movie is 120 minutes.

Explanation:

Let's use algebra to find the total length of the movie.

Let's assume that the total length of the movie is "x" minutes.

According to the given information:

Newton and his friends watch 30% of the movie, which is 0.30x minutes.

After the break, they watch the remaining part, which is 84 minutes.

So, we can set up an equation to represent the situation:

0.30x + 84 = x

Now, let's solve for "x":

0.30x + 84 = x

Subtract 0.30x from both sides:

0.30x - 0.30x + 84 = x - 0.30x

84 = 0.70x

Now, divide both sides by 0.70:

x = 84 / 0.70

x = 120

The total length of the movie is 120 minutes.
