(3y+40)+(3x-70)=180

3y+3x-30=180
3y+3x=210
3(y+x)=210
y+x=70
x=70-y

meanwhile 180-120=x therefore x=60
therefore
60=70-y y=10
so x=60 y=10

At the beginning of the bake sale merry set aside two pies for herself Kate bought half of the remaining pies for a birthday par

nirvana33 [79]

So.. .at the beginning of the sale, there was a total of "x" pies

now, let's see what happened to those pies
$\bf \begin{array}{lrlll}
&pies\\\\
&\textendash\textendash\textendash\textendash\textendash\textendash&\\

Mary&x-2\\\\
Kate&\cfrac{x-2}{2}\\\\
\textit{pies sold}&10\\\\
\textit{pies leftover}&14
\end{array}$

so, we had "x"
then Mary took 2, she left x - 2
Kate took half of that (x-2)/2
then 10 were sold, and 14 leftover

if we subtract all those figures, and solve for "x",
we should get what "x" was, so $\bf (x-2)-\left( \cfrac{x-2}{2} \right)-10-14=0$

notice, if we subtract what Mary took, and Kate, and the sold and leftover, from the original "x", we would end up with no pies :)

so.. just solve for "x"

List benefits of having a checking account

VikaD [51]

Checking Account Advantages

Checking account holders have access to online and mobile banking, ATMs and the use of debit cards and checks to make purchases or withdraw funds from the account. Many employees find checking accounts useful for direct deposit of their paychecks. With direct deposit, an employer automatically transfers a payroll amount into the employees banking account, saving time and avoiding trips to the bank to cash paychecks. Most checking accounts in the United Stated are also insured by the Federal Deposit Insurance Corporation, or FDIC, for up to $250,000, which ensures an account holder that his money is safely stored at the bank.

couldn't really find a list besides knowing its a easier way to give money when you dont have any on you.
