First, simplify the existing terms. 
21 > 3a - 21 + 9
21 > 3a - 12
Then, add 12 to both sides
33 > 3a
Next, divide both sides by 3
11 > a
This gives you a < 11.

Find m <br> we learned this last week and I forgot, please help!
lina2011 [118]

Answer:

x=8

Step-by-step explanation:

I think you mean find x, not m.

since angle DEG and angle GEF are a linear pair, they equal 180º.

18x-9 + 4x+13 = 180

22x + 4 = 180

subtract 4 from each side

22x = 176

divide each side by 22

x=8
