3/5a-1/2a=9/2

hi guys.  

There are no number thingys BUT an explanation would go down very well :/

a = 45

NO NO NO!!! Label it!!!

uuugghhhh! a = 45 units ha!

NO!!!!

ITS 45 NUMBER THINGYS

u have got to b kidding me...

ok *takes a deep breath... a = 45 number thingys.

*drum roll

YES!!! you fnally got it right!!!!! good job!!!

my pleasure :)

no one messes with me tonight, cuz i got all my gadgets ready!

$$\\\frac{3}{5}a-\frac{1}{2}a=\frac{9}{2}\\\\
\frac{3a}{5}-\frac{a}{2}=\frac{9}{2}\\\\
10\times\left(\frac{3a}{5}-\frac{a}{2}\right)=10\times \frac{9}{2}\\\\
\frac{3*10a}{5}-\frac{10a}{2}= \frac{10*9}{2}\\\\
6a-5a= 45\\\\
a=45$$

In this instance I probably did it the hard way - oh well, I have a reputation for doing this :)

Brittany can show you the easier way :)

actually melody! u did great on it! thats pretty much wat i did.. i just wrote the answer down LOL good job!

Gee thanks Brittany     LOL 

This would have been a slightly better answer I think :)

$$\\\frac{3}{5}a-\frac{1}{2}a=\frac{9}{2}\\\\
\frac{3a}{5}-\frac{a}{2}=\frac{9}{2}\\\\
\frac{6a}{10}-\frac{5a}{10}=\frac{45}{10}\\\\
6a-5a=45\\\\
a=45$$

youve done well, but youve done it 99% accurately. theres one thing you forgot:

THERE IS SUCH A THING AS NUMBER THINGYS!!!!!!

so, the correct answer Anonymous is:

A=45 NUMBER THINGYS

label your facts, son!

I am sorry Titanium         

I never was anyone's 'son'.     Maybe that is why I can't get the number thingys right.
