Topic, inequality:
Task:1
1)13 < 9+2x
2)-2x+5> there is supposed to me a line under> -2x+5> -12
3)1/4x+9<2
Task2:
Given: a> o and b< o Is a Given: 5>4. For what valuesof x is 5x>4x?

1)13 < 9+2x
Subtract 9
4 < 2x
Divide by 2
2 < x or
x > 2
=================
2)-2x+5> there is supposed to me a line under> -2x+5> -12
Use >= for that.
-2x+5>= -12
Add 2x
5 >= 2x - 12
Add 12
17 >= 2x
8.5 >= x
x <= 8.5
--------------------
3)1/4x+9<2
Subtract 9
(1/4)x < -7
x < -28
PS Use parentheses to make it clear you mean (1/4)x and not 1/(4x)
================
Task2:
Given: a> o and b< o Is a Given: 5>4. For what valuesof x is 5x>4x?
5x > 4x for x > 0, ie, positive values of x
Not clear what you mean about a & b, I don't see the relevance.
=======================================
Why are you running a math camp if you can't do problems like this?
A math camp for what?
------------------------
If you don't have a thorough understanding of the subject, the kids will burn you.
You can avoid that if you tell them up front that you'll do your best but you're not great at math. Kids are ruthless, watch out.
