3x+4+8x-28=180 what x

The equation simplified (combine like terms) would be 11x+(-24) =180.
Since adding a negative is the same as subtracting a positive, you could also write it as this: 11x-24=180. Next step is isolate the variable, so to do that you need to add 24 to both sides of the equation: 11x-24+24=180+24. This is the same as 11x=204. Now to get only one of the variable, you need to divide both sides by 11. x=18.54 repeating or x=18 6/11. Hope this helped!

<span>3x+4+8x-28=180
Add 8x to 3x
11x+4-28=180
Subtract 28 from 4
11x-24=180
Add 24 to both sides
11x=204
Divide 11 on both sides
Final Answer: x= 204/11 or 18 6/11 *Both answers are equivalent to each other.</span>

Therefore, 16,384 is the 10th term.

shepuryov [24]
To find this, simply take the largest value of the set and subtract it by the smallest value of the set. In set one, you do 24-13 to get 11

A $22,000 car depreciates by 12% per year.
asambeis [7]
$22,000 * 0.12 = $2,640
so
$22,000 - $2,640 = $19,360
so
$19,360 after 1 year.

$19,360 * 0.12 = $2,323.20
$19,360 - $2,323.20 = $17,036.80 (2 years)

$17,036.80 * 0.12 = $2,044.416
Don't round until you finish the problem.
$17,036.80 - $2.044.416 = $14,992.384 (3 years)

$14,992.384 * 0.12 = $1,799.08608
$14,992.384 - $1,799.08608 = $13,193.29792 (4 years)
ROUND
$13,193.29792 rounded to $13,193.30
