Thank you if you help me

1. 6.3333333333333333333333?

thank you for your help!

they may not be right though...sorry

My post is at the top

Anonymous's first answer is correct. However, the second is wrong.
8a4+82a=156
6a = 156 + 4  8
6a = 152
a = ? 
thanks

What math are you in?

You mean what math class? I'm in geometry.

so then 6a = 25.33333333repeating? something or other?

1.whats the value for h in 12h+9=85?
12h=76
h=76/12
h=6.333
2.whats the value of m in 6m squared + 5 = 128?
6m^2=123
6m=square root of 123
6m=11.091
m=1.85
3.what's the value of a in
8a4+82a=156
combine terms so 6a+4=156
6a=152
a=25.333
