Oh wow I forgot the basics...LOL!

 weight of a sack of sugar  =  x

weight of a sack of flour  = y

Here's a hint for #1.

We can create inequalities like this:

3x+4y ≤ 40

2y-3x ≤5

To solve this problem, try to get y to the biggest possible value. Hope this helped!!!

Woops! Sorry. I will post the answer to number 1 soon.

1) The same question was posted here: https://web2.0calc.com/questions/help_55674

2) 

Let x and y represent the numbers of Platter A and Platter B the organizer needs to purchase.. 

  x + 2y ≥ 80.  80+ hamburgers are required

  3x + y ≥ 95 . 95+hot dogs are required

  5x +8y ≥ 380.38+ chicken wings are required

  16x +20y = c 

The vertex is (x, y) = (20, 35). The other vertex close to the origin is (60, 10). The cost of that order would be $1310.

The value of an order of 20 Platter A and 35 Platter B is $1020

I've just answered your question about the S and T intersection thingy. Take a look at it! I've also given you hints on a lot of your problems.

S=9-2t

S=9-2(3s+1)

S=9-6s-2

7S=7

S=1

(Use the Substitution Property)

t=3S+1

t=3+1

t=4

Therefore, the answer is (1,4)

Hope this helped!

Here's a hint: Since you know that QSR is 90 degrees, SQR would be 25 degrees. Also, using this information, (Plus a little more) you can find out P.

Hope this helped!

Please look at this, instead of repeating a post.

Hope this helped! 

I don't think this is necessary, considering that me and a lot of others are looking at your questions right now. Be patient! 

Hi, Guest! This seems like a really hard problem. This is just a hint to help you.

I thought of this a little like the Pythagorean Theorem. If you've got some of those 3-D shapes at home, they help. I filled those in with water, and poured it into the triangle.
