**Question #1:** What 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 expression's value of it's variable is to be chosen . An equation already has the value of the variable it has .

Expression. 4+3n= .

Equation. 4+3n=19**Question #2:** What is a variable and why do we use one in algebra?

A quantity capable of assuming any of a set of values and can be in an equation or expression .**Question #3: Solve for N**

1square=2.

1circle=1.

1triangle=5.

2n=6squares&&2triangles(=22)

22

--- = 11

2

n=11.**Question #4: Solve the following equations. Show all the steps that are needed.**

A) 3n+4n+7=2n+12

7n+7=2n+12

7n=2n+5

5n=5**n=1**

B) 8n-(4+9)=11

8n-13=11

8n=24**n=3**

C) (8-3)n+7n+8=4n+40

5n+7n+8=4n+40

12n+8=4n+40

12n=4n+32

8n=32**n=4**

Question #5: For this question you need to create a T-chart and a graph to plot your data onto.

You are having a race against your friend, except you are on foot and he is on his bike. You both know that if you are on your bike, you will be faster so your friend gives you a head start of 3 minutes. If you can run 400m per minute, and your friend can bike 700 per minute, who will be the first to make to the finish line 2000m away?

Everything looks great Nathaniel, except you didn't say who won the race and you didn't create a graph. If you want to submit the graph on paper you can.

Reread your response to the first question as it contains a few gramatical errors.
