Solve |3k-2|=2|k+12|

Stella [2.4K]

Answer:

$k = 26$ or $k = -\dfrac{22}{5}$

Step-by-step explanation:

|3k - 2| = 2|k + 12|

$\dfrac{|3k - 2|}{|k + 12|} = 2$

$|\dfrac{3k - 2}{k + 12}| = 2$

$3k - 2 = 2(k + 12)$ or $3k - 2 = -2(k + 12)$

$3k - 2 = 2k + 24$ or $3k - 2 = -2k - 24$

$k = 26$ or $5k = -22$

$k = 26$ or $k = -\dfrac{22}{5}$

it's 3 miles around Westwood Park exercise Trail. after skating around the trail 5 and 1/2 times Mr Zorn lost a wheel. how many

svet-max [94.6K]

Mr. Zorn had skated total 17 miles.

Explanation

The length of the exercise trail around the Westwood park is 3 miles.

Mr. Zorn is skating around the trail 5 and 1/2 times.

So, the distance skated in 5 times $= (3* 5) miles = 15 miles$

and the distance skated in $\frac{1}{2}$ of the trail $= (3* \frac{1}{2})miles = 1.5 miles$

Thus, the total distance he had skated will be: $(15+1.5) miles = 16.5 miles \approx 17 miles$ (Rounded to the nearest mile)

Debora [2.8K]

Answer:

x=-1, y=5. (-1, 5). The first number is -1 and the second number is 5.

Step-by-step explanation:

6x+2y=4

2x+4y=18

---------------

-2(6x+2y)=-2(4)

2x+4y=18

-------------------------

-12x-4y=-8

2x+4y=18

----------------

-10x=10

x=10/-10

x=-1

6(-1)+2y=4

-6+2y=4

2y=4-(-6)

2y=4+6

2y=10

y=10/2

y=5
