Somebody once told me the world is gonna roll me
I ain't the sharpest tool in the shed
She was looking kind of dumb with her finger and her thumb
In the shape of an "L" on her forehead

Well, the years start coming and they don't stop coming
Fed to the rules and I hit the ground running
Didn't make sense not to live for fun
Your brain gets smart but your head gets dumb

So much to do, so much to see
So what's wrong with taking the back streets?
You'll never know if you don't go
You'll never shine if you don't glow

[Chorus:]
Hey, now, you're an All Star, get your game on, go play
Hey, now, you're a Rock Star, get the show on, get paid
And all that glitters is gold
Only shooting stars break the mold

It's a cool place and they say it gets colder
You're bundled up now wait 'til you get older
But the meteor men beg to differ
Judging by the hole in the satellite picture

The ice we skate is getting pretty thin
The water's getting warm so you might as well swim
My world's on fire. How about yours?
That's the way I like it and I'll never get bored.

[Chorus 2x]

Somebody once asked could I spare some change for gas
I need to get myself away from this place
I said yep, what a concept
I could use a little fuel myself
And we could all use a little change

Well, the years start coming and they don't stop coming
Fed to the rules and I hit the ground running
Didn't make sense not to live for fun
Your brain gets smart but your head gets dumb

So much to do so much to see
So what's wrong with taking the back streets
You'll never know if you don't go
You'll never shine if you don't glow.

[Chorus]

And all that glitters is gold
Only shooting stars break the mold

84=(Pi*6.7) + (2*6.7) + (2*a)

Solve for a:
84 = 2 a+34.4487

84 = 2 a+34.4487 is equivalent to 2 a+34.4487 = 84:
2 a+34.4487 = 84

Subtract 34.4487 from both sides:
2 a+(34.4487-34.4487) = 84-34.4487

34.4487-34.4487 = 0:
2 a = 84-34.4487

84-34.4487 = 49.5513:
2 a = 49.5513

Divide both sides of 2 a = 49.5513 by 2:
(2 a)/2 = 49.5513/2

2/2 = 1:
a = 49.5513/2

49.5513/2  =  24.7757:
Answer: |  a = 24.7757

Hi guest,

We do not mind a few social posts but please

If there are other social posts on the fist page then add yours underneath.

If there are no social posts on the page then you can make one for yourself.

Also the moderators in general tend to be more tolerant of social posts if they are made by members.  It is easy to become a member, you just need a username, password and valid email address.  (At least that is all that was needed last time I looked)  Plus I think your username is only ever used to confirm your membership and as a backup if you forget your password.
