An expression is a combination of numbers, operators, grouping symbols (such as brackets and parentheses) and/or free variables and bound variables arranged in a meaningful way which can be evaluated. Bound variables are assigned values within the expression (they are for internal use) while free variables can take on values from outside the expression.

This tutorial will show you how to solve linear equations with multiple steps. In order to solve for y, you need to combine like terms. First, reduce by adding constants on the left hand side together, then next, you should combine like terms, y's, and then get y by itself with undoing mutliplication using division.

expressions homework help questions for 9th grade math students.

Is there a word problem involving rational algebraic expressions?

* December 16, 2008, 5:13 am*

By showing me correct steps and procedures to solve algebraic expressions,etc.

Hopefully simplifiying expressions so I can move on in algebra.

Help me understand algebraic expressions better.

I Would like to re-learn all the math lessons I\`ve had since the 6th grade, Mostly because i slept throughout the 6th grade to 9th grade. I\`ll be stuck in 9th grade again next year, and i don\`t want it to happen again.. (And i was watching Clannad and i suddenly got jealous of Kotomi Ichinose) yes, nerdy, i know. And i don`t care.

To prepare for the 9th grade.

I hope to get a better understanding on how to factor out expressions.

I ned to take some test ,so i ned to learn more about 9th grade math.

Because i am in 9th grade n im supposed 2 be in the 11th grade and i was told this could catch me up.

Understand evaluating expressions with decimals more better.

It will help me with my son who`s entering 9th grade but struggles to understand teacher`s explanations and this will allow for him to practice at home.

I am a resource math teacher to 8th and 9th graders and I need more resources.

To learn how to work word problems, algebraic expressions with variables, rates,y=mx+b or y=mx-b, and knowing what these variables stand for on a graph, fractions conversions etc.

I hope it will help me get an understanding of problem solving by using algebraic expressions.

I teach math to 9th grade -12th grade at a small city school in North Carolina. Knowing that each student in NC has to score levels 3 or 4 on the EOC Algebra 1 test to graduate, any real-life application type problems would be beneficial to the success of my students. Knowing also that matrces are heavily tested on the NC EOC test, this website appears that it would be helpful. Our textbooks do not offer many examples of matrices . Thank you.
