I just need 6, 7, 8, 9, and 10. Please help me if you know how to do this..

Answer:

Step-by-step explanation:

#6  

a       n

---- = ----    Solve for a.  Note that if we multiply both sides of this equation by

m       p                                     n

                  m, we get a = m * ----

                                                  p

                                                                                    m*n

                    and this simplifies to a = mn/p or  a = ---------

                                                                                       

#7     Solve mx = np for x.  We want to isolate x on the left side.  Dividing

both sides by m isolates x on the left and adds the divisor m on the right:

                            np

mx = np  =>  x = ------

                              m

#8    Solve c - x = d + r  for x       We want -x alone on the left side.  Accomplish this by subtracting c from both sides, obtaining:

-x = d + r - c.       Now multiply both sides by -1, obtaining x = -d - r + c
