Question 184897: Jenny wants to utilize a portion of her garden for growing flowers. Being a designer herself, she visualizes a triangular area with different lengths for each side. For this Jenny decides to keep a side of the triangular area 3 feet shorter and the other 2 feet longer than the third side. She also wants to restrict the perimeter of the triangular area to 32 feet, so that it does not cover a huge area of the garden. Determine the maximum length of each side of the triangular area that Jenny has visualized

Question 187311: Hello. I have a question that I can't understand how to solve. Any help would be appriciated. Thank you!
Solve, graph on a number line and write your answer in set-builder notation.
- x/2 + 4 < 3x/2 + 8
It's - x over 2 and 3x over 2. I did not know how to do fractions on here so used the / sign.

Question 187773: I need your help on solving an inequality. I know how to solve it but I don't understand the test points. For example:
x^2+6x<16
I know that the problem gets put in standard form
x^2+6x-16<0
and then it is factored
(x+8)(x-2)
then you set the factors equal to zero for the x intercepts
x+8=0 x=-8 and x-2=0 x=2
but I don't understand the test points
for example
(-2,8)
(-8,2)
(-8,-2)U (8,8)
(-8,-8)U (2,8)
please explain

Question 187797: hi, i have a lot of trouble with word problems and was wondering if you could help. here is the problem.
In your economics 101 class, you have scores of 68, 82, 87 and 89 on the first four of five tests. To get a grade of B, the average of the first five test scores must be greater than or equal to 80 and less than 90. Solve an inequality to find the range of the score that you need on the last test to get a B.
i did (68+82+87+89+x)/5 > 80 but i dont think that really helps..
thank you!

Question 188295: Can you help me solve this inequality? This is the question:
Option 1: C=_3x+32________________
Option 2: C=__6.50x_______________
How many hours would you have to rent the court so that the monthly cost of option 1, is less than option 2. Set up an inequality and show your work algebraically using the information in part a. Round to 3 decimal places if necessary.
This is what I have gotten so far:
32+3x<6.50x
-3x -3x
= 32<3.50x
32/3.50x<3.50x/3.50x
