  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
7. 9 less than 3 times a number : 9-3x 8. four more than eight times a number : 8x+4

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.
