1/2 (5-7x) = 8- 4x+6

1 answer:

7 0

1/2(5-7x)=8-4x+6
-7/2x+5/2=-4x+14                       Simplify both sides
1/2x+5/2=14                               Add 4x to both sides
1/2x=23/3                                   Subtract 5/2 on both sides
2*(1/2x)=2*(23/2)                       Multiply both sides by 2
x=23 - Final Answer

professor190 [17]

Well, from 2008 to 2010 is just 2 years, so let's say the initial amount is the 19300 from 2008, how many will it be in 2010?

$\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &19300\\
r=rate\to 20\%\to \frac{20}{100}\to &0.20\\
t=\textit{elapsed time}\to &2\\
\end{cases}
\\\\\\
A=19300(1+0.2)^2$
