Answer:
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.
