Answer:
the width is 17.5 feet and the length is 82.5 feet.
Step-by-step explanation:
The house has a rectangular shape and we know that the length is 5 feet less than 5 times the width.
We will call the width x, thus, the length would be represented as 5x-5 (5 less than 5 times the width).
Since Darrin is going to hang garland around the perimeter of the house, we know that the perimeter is 2 times the length plus two times the width and this equals 200.
Let's write this in algebraic form
Therefore, the width is 17.5 feet.
Now, the length is 5x-5, thus substituting the 17.5 in this equation we have:
feet
Therefore, the width is 17.5 feet and the length is 82.5 feet.
Answer:
They make <u>2000</u> brown crayons on that day.
Step-by-step explanation:
Given:
Crayola makes 3 red crayons for every 2 brown crayons.
On Tuesday, their factory made 1,000 more red crayons than brown.
Now, to find the number of brown crayons they make that day.
Let the numbers of brown crayons be
So, the number of red crayons =
As given, 3 red crayons for every 2 brown crayons.
So, the ratio is 3:2.
Thus, 3 is equivalent to 2.
So, 1000+ is equivalent to
Now, to get the number of brown crayons by using cross multiplication method:
<em>By cross multiplying we get:</em>
<em>Subtracting both sides by 2</em><em> we get:</em>
Therefore, they make 2000 brown crayons on that day.
