Before we start, let’s change length to a different variable. We will call it “y”.
Thus x = 5’ and y = 10’

Based on information from original cornhole opening we know:
(x)*(y) = 50ft^2 also we know y = 2x since 10 feet is twice the amount of 5 feet. Therefore the relationship of x and y can be written as the following (in terms of x only):

(x)*(2x) = 50 or 2x^2 = 50. Check your work to see that solving for x = 5 and y = 10 which matches the given information.

Since the problem states uniform growth of the new opening we can set our equation equal to 84 and solve for new value of x

2x^2 = 84 which gives value of 6.48’ Also from before y = 2x thus new y = 12.96’. Checking would give total area of 83.98’ which is slightly lower due to rounding.

You could also state new value of x would be sqrt of (84/50) since that would be ratio of impact.

Either way the width would increase 1.48’ and length would increase by 2.96’.

Alecsey [184]
Option B is not a solution.

5y=3x+15
5(12)=3(-15)+15
60=-45+15
60≠-30

This week laptops are 25% off. If a laptop costs $340, what is its sale price?
Alexandra [31]

____________________________________________________

Answer:

Your answer would be $255

____________________________________________________

Step-by-step explanation:

To solve these kind of problems, what we have to do is find how much of 340 is 25%, and then subtract that number to the original price.

Let's give you some important information in the text:

  • 25% off
  • $340

With the information above, we can solve our problem.

First, we would need to find how much of 340 is 25%, and to do that, we would multiply 340 by 0.25:

340*0.25 = 85

When you solve, you should get 85. But, you're not done yet, we need to find out how much the sales price is, not how much of it is discounted.

In order to find the sales price, we would get our original number (the number it originally cost), and subtract it with the amount of money it's removing (85).

In this case, we would subtract 340 by 85.

340-85=255

Your FINAL answer should be 255

The sales price of the laptop would be $255.
