A. 3.15
B. 3.56
C. 4.67
D. 10.67

Answer 2

You have a property of this too.

Answer 3

It says \(EF = \dfrac{CD+ AB}{2}\)
Replace the given information in and solve for x

Answer 4

\[4x = \frac{ 9 + 5x + \frac{ 5 }{ 3 }}{ 2 }\]

Answer 5

yup

Answer 6

now, solve for x

Answer 13

\[2*4x = \cancel 2*\frac{ 9 + 5x + \frac{ 5 }{ 3 }}{ \cancel 2 }\]

Answer 14

It is???

Answer 15

8x = 9 + 5x + 5/3

Answer 16

ok, combine like term from the right hand side, what do you have?

Answer 17

9 + 13x + 5/3

Answer 18

9 + 5/3 =??

Answer 19

9 = 27 /3, right?

Answer 20

so 27/3 + 5/3 = 32/3, right?

Answer 21

hence, it is
8x= 5x + (32/3)

Answer 22

Now, -5x both sides,
