We would do what’s in the parentheses first, so 912-14 which is 898. Then in our order of operations comes multiplication. We would do 5 x 898 which is 4,490. Then comes addition. 4,490 + 0.5 which is 4,490.5. Hope this helped!

To borrow money, you pawn your guitar. Based on the value of the guitar, the pawnbroker loans you $

Nonamiya [84]

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &\$1472\\
P=\textit{original amount}\to& \$1080\\
r=rate\\
t=years\to &\frac{1}{12}
\end{cases}
\\\\\\
1472=1080\left(1+r\cdot \frac{1}{12}\right)$

notice, it was pawned for only 1 month, so the "yearly" rate is for 1 month, which is 1/12 of the year, since a year has 12 moths

you'll get a rate in decimal terms, to get the % amount, just multiply it times 100

= 110

This means that the speed of the train is 110 km per hour.

So, the constant of variation is 110.
