This further simplifies to solution,

x=-\dfrac{39}{3}\Longrightarrow\boxed{x=-13}

To get on a certain toll road a driver has to take a card that lists the mile entrance point. The card also has a timestamp. Whe
kolezko [41]

Answer:

Step-by-step explanation:

This can happen because of the timestamp on the toll card. When you pass through the initial entrance point the timestamp marks the exact moment you passed. When you pass through the exit toll point the individual subtracts the current time from the time you entered the initial toll entrance. From this, he can easily determine the average speed that you were driving at. If the average speed is higher than the speed limit, it means that at some point between the two toll booths you were speeding and therefore they can give you a speeding ticket.

mario62 [17]
Suspecting that his parents are going to give him $1,300 continually you would solve like this

$120,000-$100= $19,900
$19,900/$1,300= 92.23
92.23 is the amount of $1,300 donations it would take from his parents, so if he was getting $1,300 month it would take 92.23 months
