1. 3x+8 : Three times a number and eight
   
2. 7x+5x : Seven times a number and five times a number
   
3. 5(x+8) : Five times the sum of a number and eight
   
4. 8-3x : Eight decreased three times a number
   

For the bottom of the first part of the test we had to write the following statements as algebraic expressions..

5. 9 centimeters less than three fourts of length x : 3/4x-9
6. Seven decreased by four times a number : 7-4n

For the second part of the test we had to make a t-chart, graph and figure out the algebraic equation for the following problem ..
This is my T-chartThe patter : x = Figure number, Starting with one going up by one.
y = Number of tiles, starting with four and adding three each time.

Here is my Graph

How to get the answer

• x=Figure number
• y=Number of tiles
  
• The algebraic equation is 3x+7
