Answer:

x = 7

Step-by-step explanation:

Given

\frac{4}{3}x - \frac{1}{3} = 9

Required

Solve for x

\frac{4}{3}x - \frac{1}{3} = 9

Add \frac{1}{3} to both sides

\frac{4}{3}x - \frac{1}{3} + \frac{1}{3} = 9 + \frac{1}{3}

\frac{4}{3}x = 9 + \frac{1}{3}

Take LCM

\frac{4}{3}x = \frac{27 + 1}{3}

\frac{4}{3}x = \frac{28}{3}

Multiply both sides by \frac{3}{4}

\frac{3}{4} * \frac{4}{3}x = \frac{3}{4} *\frac{28}{3}

Evaluate the left hand side

x = \frac{3}{4} *\frac{28}{3}

x = \frac{28}{4}

Divide 28 by 4

x = 7

The answer would be 18.2 gallons because they used up 5.8 gallons, they still have 12.4 gallons that they did not use and in order to get the original amount of gas they had before the trip, you would add up 12.4 and 5.8 to get the Original amount. Hope this helps.

TiliK225 [7]

The price of the book is 125% higher than the price of the notebook if the price of a notebook is 20% less than the price of a book.

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

Let x is the price of the book

And y is the price of the notebook,

Then,

y = x- 0.20x = 0.80x

x = (1/0.80)y

x = 1.25y

Thus, the price of the book is 125% higher than the price of the notebook if the price of a notebook is 20% less than the price of a book.
