Answer:

x=2

Step-by-step explanation:

Step 1: Add 2x to both sides.

4x−3+2x=−2x+9+2x

6x−3=9

Step 2: Add 3 to both sides.

6x−3+3=9+3

6x=12

Step 3: Divide both sides by 6.

<u>6</u><u>x</u><u> </u><u>=</u><u> </u><u>1</u><u>2</u>

If your car gets 28 miles per gallon and you travel 30 miles round-trip to work five days a week, how much do you pay each 4-wee

disa [49]

Answer:

You'd pay $65.35 every 4 weeks

Step-by-step explanation:

First you have to gather all the miles.

30 miles x 5 = 150

So that is 150 miles/per week

Then you have to devide the miles by how many gallons per gas you travle.

150/28 miles per gallon = 5.3571....

That how many gallons you'll need a week.

Now, you times the gallons by the price of the gas

5.3571... x $3.05 = $16.3392...

Finally you times the amoutn of money for a week time 4 weeks.

$16.3392... x 4 = $65.35 (to the two decimal mark)

Hope this helped you! : )
