Answer:
Step-by-step explanation:
Five is <em>one-eighth</em> of forty, so relatively proportional to that, <em>one-eighth</em> of twenty-four is three, so you do this:
24 = 2x + 10
- 10 - 10

Answer:
Step-by-step explanation:
We can write the following proportion:
We know that the original perimeter of the Pentagon is 921 feet. So, substitute 921 for "old perimeter."
We are going to use a scale of 3 cm = 307 feet. Since the 307 feet corresponds to the original perimeter, we are going to substitute 307 for "old scale factor" and 3 for "new scale factor."
This gives us:
So, to find our scaled perimeter, we just need to find x.
Cross multiply:
Divide both sides by 307:
In other words, the total perimeter of Sawyer's drawing will be 9cm.
And we're done!
Iva got the correct answer and Lorraine's answer was incorrect. Lorraine did everything correct except 1 common mistake at the end. At the end of the problem, you have the equation 2x = 20. Instead of dividing by 2, it's possible that Lorraine mixed up the steps and divided by 10 on both sides to get x = 2. You're supposed to divide 2x by 2 and 20 by 2 to get a quotient of 10.
