-8 < 2x-4 < 8

Add 4 to all sides:

-8 + 4 < 2x -4 + 4 < 8 + 4

Simplify :

-4 < 2x < 12

Divide all sides by 2:

-4/2 < 2x/2 < 12/2

Simplify to get the answer:

-2 < x < 6

A car travels 83 7/10 miles on 2 1/4 gallons of fuel which is the best estimate of miles the car travels on one gallon of fuel

To solve this problem we can use proportion, but first its nice to transform our fraction into improper fraction, so
$83 \frac{7}{10}= \frac{837}{10}$
and
$2 \frac{1}{4}= \frac{9}{4}$
Now we can make proportion

$\frac{837}{10}$ -------------------------- $\frac{9}{4}$ of fuel
x----------------------------- $1$
Now we can cross multiply

$x= \frac{ \frac{837}{10} }{ \frac{9}{4} }= \frac{837}{10}* \frac{4}{9} = \frac{3348}{90}=37.2$ - its the result

A linear function is a polynomial function in which the variable x has degree at most one: {displaystyle f (x)=ax+b}. Such a function is called linear because its graph, the set of all points {displaystyle (x,f (x))} in the Cartesian plane, is a line.
