Question

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=

Answer 1

To solve this problem, we can set up a proportion.

Let x be the number of minutes in the documentary. So, if one-fourth of the documentary is 70 minutes, then the whole documentary is x minutes.

We can set up the following proportion:

1/4 = 70/x

To solve for x, we can cross multiply:

1 * x = 4 * 70

x = 280

Therefore, there are 280 minutes in the documentary.

Answer 2

Marcus and his twin sister Marcie decide to save $25 each week to buy a video console. How long will it take for them to save $675?(1 point)
x=

Answer 3

To find out how long it will take Marcus and Marcie to save $675, we can set up an equation.

Let x represent the number of weeks it takes for them to save $675.

Since they save $25 each week, Marcus and Marcie save a total of 2 * $25 = $50 each week.

So we can set up the following equation:

$50 * x = $675

To solve for x, we can divide both sides of the equation by $50:

x = $675 / $50

x = 13.5

Since we can't have a fraction of a week, we round up to the nearest whole number.
Therefore, it will take Marcus and Marcie 14 weeks to save $675.

Answer 4

wrong

Answer 5

My apologies for the mistake. Let's calculate it correctly:

To find out how long it will take for Marcus and Marcie to save $675, we can set up an equation.

Let x represent the number of weeks it takes for them to save $675.

Since they save $25 each week, Marcus and Marcie save a total of 2 * $25 = $50 each week.

So we can set up the following equation:

$50 * x = $675

To solve for x, we can divide both sides of the equation by $50:

x = $675 / $50

x = 13.5

However, we cannot have a fraction of a week, so we need to round up to the nearest whole number.

Therefore, it will take Marcus and Marcie 14 weeks to save $675.

Answer 6

so what does x=

Answer 7

Apologies for the confusion. Let's recalculate.

To find out how long it will take for Marcus and Marcie to save $675, we can set up an equation.

Let x represent the number of weeks it takes for them to save $675.

Since they save $25 each week, Marcus and Marcie save a total of $25 + $25 = $50 each week.

So we can set up the following equation:

$50 * x = $675

To solve for x, we can divide both sides of the equation by $50:

x = $675 / $50

x = 13.5

However, we cannot have a fraction of a week, so we need to round up to the nearest whole number.

Therefore, x = 14. It will take Marcus and Marcie 14 weeks to save $675.
