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=
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.
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=
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.
wrong
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.
so what does x=
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.
