1)   Solve: 2x + 5 + 3x = 95
     [show ALL steps for full credit]
2)   Simplify:   (2.3 x 104)(5.0 x 103)

3)   Write 7/9 as a decimal and a percent.

4)   Simplify:    (2xy)(3x2y)
                     6xy2

5)   Combine like terms and simplify:   9(x - 3) - 4(x - 5)




                                                              2
