HELP!!<br> can someone lease help me with #11 and #12
Fiesta28 [93]

11. The two angles are vertical angles, which mean they are equal to each other.

14x - 5 = 13x

Add 5 to both sides:

14x = 13x + 5

Subtract 13x from both sides:

x = 5

12.  The two angles are supplementary and when added together need to equal 180 degrees.

5x -20 + 3x = 180

Combine like terms:

8x -20 = 180

Add 20 to both sides:

8x = 200

Divide both sides by 8:

x = 200 /8

x = 25

What is the sum of 9c+(8+3c)?
mixas84 [53]
<span>9c+(8+3c)      
9c+8+3c     (collect like terms)

9c+3c+8
12c+8

12c+8 is the answer.
im not sure if your teacher also wants the answer to be in simplest form so im going to do that below as well:

12c+8      (4*3=12 and 4*2=8. you can take out a 4 from those 2 numbers)

4(3c+2) (this is the simplest form of </span>9c+(8+3c)<span>)
