Carly, Brittany, and Lauren streamed one-fourth of an eight-episode documentary. If 70 minutes of the documentary have been watched, how many minutes are in the documentary?(1 point)
n=
Let x be the total number of minutes in the documentary.
One-fourth of the documentary is x/4 minutes.
The equation is x/4 = 70 minutes.
Multiplying each side of the equation by 4, we get x = 70 * 4 = <<70*4=280>>280 minutes.
The documentary has 280 minutes. Answer: \boxed{280}.
