Answer:

CD = 4

Step-by-step explanation:

GH bisects CF  <u><em>means</em></u>  CF = 2 CD

CF = 2 CD

⇔ 2y - 2 = 2×(3y - 11)

⇔ 2y - 2 = 6y - 22

⇔ 22 - 2 = 6y - 2y

⇔ 20 = 4y

⇔ y = 5

<u>Calculating CD ,For y = 5</u> :

CD = 3y - 11

     = 3(5) - 11

     = 15 - 11

     = 4

Answer:

We conclude that the percent of decrease = 20%

Step-by-step explanation:

Given

  • Original amount = $3930
  • Amount of decrease = $3930 - $3144 = $786

Using the formula

Percent of decrease = ( amount of decrease / orignal amount × 100 ) %

                                   = ( 786 / 3930 × 100 ) %

                                    = ( 0.2 × 100 ) %

                                    = 20%

Therefore, we conclude that the percent of decrease = 20%
