Juan Said:any tips in solving algebra age problems?We Answered:Yes. First, examine the problem and find the exact question being asked.
"What is Ann's age now?"
"What will Achbar's age be three years from now?"
Let that value be x.
Then, express the other parts of the problem as equations using x:
"Fred is three times as old as Ann is now." Fred's age is thus 3x.
"Two years from now, Fred will be twice as old as Ann is then."
How old will Fred be two years from now? 3x + 2
How old will Ann be two years from now? x + 2
"Two years from now, Fred...

Mattie Said:Are there any sites that offer all of the tutorials for the TI-83 Plus calculator?We Answered:Not quite; it would certainly nice if a compilation of all these tutorials existed, but unfortunately, no such place is on the Internet (so I've found).
Your best bet would probably be just to do a search in your favorite search engine for whatever you're looking for, with "TI-83" in the query. That way, it should return more relevant topics.Julie Said:Good Website for High School Algebra competition Preperation?We Answered:I ahve had my share of High School and college math courses.

Greg Said:Algebra 2 teachers, Please help?We Answered:Personally I prefer the McDougle-Littell text. I tutor in the evenings at a local Sylvan Learning Center and find that the text presents the data in an easily understood format and it is student friendly.
Good Luck with you schooling ...Morris Said:Help with a few Algebra 2 concepts, please?We Answered:1. use your LCM (least common multiple ) of 3 and 6
which is 6
so multiply both sides by 6
6( (x/3) - (y/6) ) = 1 (6)
2x - y = 6
then manipulate the variables
- y = 6 - 2x
- y = -2x + 6
y = 2x...
Joanne Said:I Don't Know How to do these Algebra 2 equations, Please help? Something about substitution?We Answered:well what u do is subsitute what each of those are....eg....since y=5x...u would put 5x in place of the y in (4x + 2y= 7)....to get
4x + 2(5x)= 7 --> 4x + 10x= 7 --> 14x=7 --> x= 2
and u would do that for the rest of them .....!!!Veronica Said:How do you solve these equations (algebra 2)?We Answered:1.
5/4 = n-3 / n-4
5(n-4) = 4(n-3) <-- cross multiplying
5n - 20 = 4n - 12 <-- opening the brackets
5n - 4n = -12 -...
Melinda Said:Hyperbola's and Algebra mixed wih Geometry?We Answered:Parabolas, hyperbolas, and ellipses are all solutions sets of equations of the form f(x,y) = 0, where f is a polynomial of degree too.
Consider the equation of general form Ax^2 + By^2 + Cx + Dy = 0.
When A and B are positive you get an ellipse (and when they're equal you get a circle, which is a special case of an ellipse).
When A is positive and B negative, you get a hyperbola.
When B is zero, you get the inbetween case of a parabola.Ronald Said:HELP!! need the questions to algebra 2 lesson 5...
Olga Said:help with solving (please show the steps) three algebra practice problems for a test tomorrow...?We Answered:- 4(2x - 6) + 7x = 5x + 24
- 8x + 24 = - 2x + 24
6x = 0
x = 0
Answer: x = 0
Proof:
- 4(2[0] - 6) + 7(0) = 5(0) + 24
- 4(0 - 6) + 0 = 0 + 24
- 4(- 6) = 24
24 = 24
------------
√(3x + 7) = 3x + 5
9x² + 15x + 15x + 25 = 3x + 7
9x² + 27x = - 18
x² + 3/2x = - 2 + (3/2)²
x² + 3/2x = - 8/4 + 9/4

"X" so to get x by itself you need to subtract 2 from both sides
|x|+2=4
-2 = -2
Now your left with |x|=2
those little lines just mean "absolut value" that just means anything that is inside will have a final answer that is a positive number. And since x already is a...
