growing post

Question #1What is the difference between an algebraic expression and an equation (hint: one contains this and the other doesn't)? Give an example of both an expression and an equation.

an algebraic expression uses a letter for the unkown but an equation just has numbers
Expression: 5(n) + 40= 65 equation: 45+69=114
n= 5

Question #2What is a variable and why do we use one in algebra?

A quantity is capable of assuming any of a set of values & can be used in a expression or an equation.

Question #3 Solve for N
1 square - 2.1 circle - 1.1 triangle - 5.2n = 6 squares and 2 triangles (=22)
the represents eleven!

Question #4 Solve the following equations. Show all the steps that are needed.

a) 3n + 4n + 7 = 2n + 12
b) 8n - (4+9) =118n - 5 = 118/8 11/8n = 1.375
c) (8-3) n + 7 n + 8 = 4n + 40.

Number 5 will be here soon. it'll be here wen i learn how to get a picture from paint to this spot!

On the top of your post you have to click on to the add image picture thingy on the top right of your post. It is partly under the edit Html It has blue on the top and a mountain on the bottom. Then you should be able to upload your picture from there to your post

renegade make sure that you are saving your picture in paint as either a .jpeg or .gif file. The default is a .bmp file and you cannot load this type of file to blogger.

renegade take a look at your notes because you don't have the right definition for an expression. An expression has a variable in it just like an equation, its just that there is something different between these two variables (maybe the number of possible values that they can have.)

Look over your answers again for question 4 as you have some mistakes

renegade your mark is 9/30. You didn't make any of the corrections that I suggested, or created the growing post on paper.
