7x-3 = 18
+3 for both sides
7x = 21
devide 7 for both sides
x = 3
309 times 692 ***********************
"25%" means "0.25"
"of" means "times"
You said 11 members = 0.25 x (the club)
Divide each side by 0.25 : The club = (11 / 0.25) =<em> 44 members
</em>This is as fast as I can type.<em>

Answer:</h3>
<u>By angle bisector property</u>,
- 11x + 23 = 8x + 35
- 11x - 8x = 35 - 23
- 3x = 12
- x = 4°
So, <u>m∠ABD</u> = 8x + 35
<u>m∠CBD</u> = 11x + 23
<u>m∠ABC</u> = 67° + 67° = 134°
