h doesn't change     (but k does)

G + 16 = 3/5 (40 - G)

G + 16 = 24 - 3/5 G

8/5 G = 8

G = 8 * 5/8 = 5                                I do not know why the equation with J in it was included.....

Botch had 67 dollars after he  gave 1/4 to his friend. How many dollars did he have to start?

If Botch gave away 1/4 of his cash, he has 3/4 left and that is 67 dollars.

x = the amount he had at the start

3/4 * x = 67   multiply both sides by  4/3 to get:

     x = 67 * 4/3 =~~~  89.33

It took Mr I   5 hours to drive 240 miles        avg speed   =   240 / 5 = 48  m /hr for the trip

    If we look at ONLY the time he was actually  driving, he drove 240 miles in 4 hours = 60 m/hr

Average speed = total distance / total time

                         = (50 m/hr *4 hr     + 30 m/hr *1 hr) / ( 4+1 hrs)

                          = 230 miles / 5 hrs = _______________ m/hr

See if you can do the others...........

3x^2-8x-2 =

3 (x^2 - 8/3x)   -2     complete the square for 'x'

3 ( x -4/3)^2   - 48/3 - 2

3 (x - 4/3)^2 - 18         You can finish I hope!    

How to solve this exponential equation?

10 00000 * .9^t = 0

         .9^t   must equal 0

              which is not possible ........

Squares have each of their angles = 90 degrees

   an equilateral triangle has internal angles of 60 degrees.....can you deduce what the angle CDB is with this info?

There are 16 oz in a pound   so the puppy weighs   105 /16   pounds....    you can finish?
