Answer:
<em>The length and width of the deck will be 11 meters and 9 meters respectively. </em>
Step-by-step explanation:
The length of the rectangular deck is meter and width is meter.
The perimeter of the deck should be 40 meters. So, the first equation will be...
The difference between twice the length and twice the width should be 4 meters. So, the second equation will be....
<u>Adding equation (1) and (2)</u>, we will get.....
<u>Now plugging this into equation (1)</u>, we will get....
So, the length and width of the deck will be 11 meters and 9 meters respectively.

Answer:
<em>For each horizontal foot, the roller coaster changes </em><em>6 feet</em><em> of height.</em>
Step-by-step explanation:
Across a horizontal distance of 25 feet, a roller coaster has a steep drop.
So the run is 25 feet.
The height of the roller coaster at the bottom of the drop is -150 feet. (Negative sign is given because it is measured from the top to bottom)
So the rise is 150 feet.
The slope of the roller coaster is,
Slope of 6 means, for 1 unit of run, the object has a rise of 6 units.
Therefore, for each horizontal foot, the roller coaster changes 6 feet of height.
