$(7x^{2})(2x^{3} +5)( x^{2} -4x-9)
$
$(14 x^{5} +35 x^{2})( x^{2} -4x-9)$
= $14 x^{7} -56 x^{6}-126 x^{5}+35 x^{4}-140 x^{3}-315 x^{2}$

If a car can travel 220 miles on 12 gallons of gas, how many gallons

vampirchik [111]

Set up a ratio of known to unknown:

Let X = the amount of gas needed for 500 miles:

220/12 = 500/x

Cross multiply:

220x = 6000

Divide both sides by 220:

X = 6000 / 220

x = 27.27 gallons (round answer as needed).

The model represents an equation. What value of x makes the equation true?

ch4aika [34]

Let's build the equation counting how many x's and 1's are there on each side.

On the left hand side we have 5x's and 8 1's, for a total of $5x+8$

On the left hand side we have 3x's and 10 1's, for a total of $3x+10$

So, the equation we want to solve is

$5x+8 = 3x+10$

Subtract 3x from both sides:

$2x+8 = 10$

Subtract 8 from both sides:

$2x=2$

Divide both sides by 2:

$x=1$
