Answer:

14 gallons

Step-by-step explanation:

First determine the amount of miles per gallon her car will go by dividing the amount of miles by the amount of gallons.

228/9.5 = 24 miles per gallon

This means on a trip of 336 miles she will use 14 gallons.

336/24= 14 gallons

Answer:

Step-by-step explanation:

To create an augmented matrix, we need to transfer the coefficients of each system of equations into its respective place in the matrix. The first row will be the coefficients of the first equation and so on. The number to the right of the equals sign is the last column of the augmented matrix.

$\left[\begin{array}{ccc|c}1&-1&8&8\\3&-9&1&-1\\8&1&0&0\end{array}\right]$
