Angles C and D are supplementary, meaning they add up to 180 degrees. So, if we add 8u-48 to 5u+46, we get 13u-2. We set that equal to 180, so 13u-2=180. Add the two, so 13u=182. Divide the 13, so u=14. To double check, plug in 14 to both expressions. 8(14)-48 and 5(14)+46. 8(14)-48 is 64. 5(14)+46 is 116. If you add 64+116, you get 180, which proves your answer right! So u= 14

1).  $2,700 is  (2,700/6,000) = 45% of  6,000.

      It took 6 years to earn it, so it earned (45%/6) = 7.5% each year.
      That's the simple-interest rate.

2).  The investment earns 4.5% each year, so it earned 9% in 2 years.

      The $1,150.65 is the 9% of the original investment.  Call it V.

      1150.65 = 0.09 x V .

Divide each side by 0.09 :

         V  =  1150.65 / 0.09  =  $12,785 .

3).  There are 18 marbles in the bag all together.

a).  8 of them are green.  If you close your eyes and pull out 1 marble,
the probability that it's a green one is
                                                               8/18 = 4/9  =  44.4% .

b).  If it was a red marble, and you put it in your pocket, then
there are only 17 in the bag now, and 8 of them are still green.

If you pull another one, the probability that it's green is

                                                               8/17  =  47.1% .

5).  There are 10 marbles in the bag all together.
(The second sentence doesn't say anything, and doesn't mean anything.)

If you pull out a silver marble and put it in your pocket, then
there are 9 marbles in the bag, and 2 of them are orange.

The probability of pulling an orange marble now is

                                  2/9  =  22.2% .
