The answer: " k = -10 " .
__________________________________________
Given: (- 6/5) k = 12 ; Solve for: "k" ;
__________________________________________
Multiply each side of the equation by "5" ; to get rid of the "fraction":
5* (-6/5) k = 12 * 5 ;
to get:
- 6 k = 60 ;
Divide each side of the equation by "-6" ;
________________________________________
- 6 k / 6 = 60 / 6 ;
to get:
-1 k = 10 ;
_______________________
Divide each side of the equation by "-1" ;
to isolate "k" on one side of the equation ; and to solve for "k" ;
________________________
- 1 k / -1 = 10 / -1 ;
________________________
to get: k = -10 .

<u>Step-by-step explanation:</u>
Here we have , A laptop lock has a 4 digit combination. Each character can be any digit between 0-7. The only restriction is that all 4 characters cannot be the same (e.g. 0000, 1111, 2222,... etc.). We need to find How many combinations are possible .Let's find out:
The first digit has 8 choices (can be all of them), the second digit also has 8 choices. The third and fourth digits also have 8 choices.
Multiply them together you get:
⇒
⇒ possible combinations.
But since all 4 characters cannot be the same, we subtract 8 from 4096 (there are 8 combinations which the 4 characters are the same: 1111, 2222, 3333, 4444, 5555, 6666, 7777, and 0000) and we get :
⇒
⇒
Therefore, are possible combinations .
Let width be x
Length; 6+2x
p=2(l+w)
7878=2((6+2x)+x)
7878=2(6+3x)
7878=12+6x
7878-12=6x
7866=6x
7866/=x
1311=x
Therefore, the width is 1311 meters, length is (6+2(1311)=2628 meters

Answer:
31.42 cm approx.
Step-by-step explanation:
it is what it is...
Answer:
<h3>The answer is 32cm</h3>
Step-by-step explanation:
Circumference of a circle = 2πr
where
r is the radius
To find the radius of the mat substitute the value of the circumference into the above formula and solve for the radius
Circumference = 200cm
200 = 2πr
Divide both sides by 2π
r = 31.83098
We have the final answer as
<h3>radius = 32 cm to the nearest whole number</h3>
Hope this helps
