Answer:

\Huge \boxed{N=-18}

Step-by-step explanation:

To solve this problem, first you have to isolate it on one side of the equation.

First, multiply 3 from both sides.

3*2/3n=3(-12)

Solve.

3*-12=-36

2n=-36

Next, divide 2 from both sides.

2n/2=-36/2

Solve.

-36/2=-18

Therefore, the correct answer is n=-18.

Answer:

-1/18

Step-by-step explanation:

Let's multiply left and right by 3n:

2 = -12 * 3n =>

-36n = 2

now divide by -36:

n = 2/-36 = -1/18

Shkiper50 [21]

Answer:

$246

Step-by-step explanation:

The price of the product is $390, after 6 months the price is marked down by 10% which is $39 so the total will be $351. After another 6 months the price is marked down again by 30%, which is $105 and 3 cents ($105.3). For a total of $245 and 7 cents ($245.7).  To round the number you only need to look at the number after the decimal which is 7 in this case. Any number bellow 5 counting 5 in it, will stay the same number, any number above 5 without counting 5 will be the next number. So $245.7 rounded to the nearest dollar will be $246.

Hope it was helpful ^^ <3

Good Luck
