Question

8,5+12+(−4,18k)=15+8,5−4,28k. k=

Answer 1

Ответ:

k=3

Пошаговое объяснение:

-4,18k+4,18k=15+8,5-8,5-12

k=3

Answer 2

To solve for the value of k in the equation:

8.5 + 12 - 4.18k = 15 + 8.5 - 4.28k

You can start by simplifying both sides of the equation:

On the left side, combine like terms:

(8.5 + 12) - 4.18k = 20.5 - 4.18k

On the right side, also combine like terms:

(15 + 8.5) - 4.28k = 23.5 - 4.28k

Now, you have the equation:

20.5 - 4.18k = 23.5 - 4.28k

To isolate k, move the terms with k to one side of the equation and the constants to the other side. You can do this by adding 4.28k to both sides and subtracting 20.5 from both sides:

20.5 - 4.18k + 4.28k = 23.5 - 20.5

Now, simplify:

0.1k = 3

To solve for k, divide both sides by 0.1:

k = 3 / 0.1

k = 30

So, the value of k is 30.
