Absolute value equation question, pls explain if u don't I will literally die ​
ladessa [460]

Answer:

-10

Step-by-step explanation:

I dont want you to "Literally die" so heres the explaination:

The absolute value mean always a positive number. So if a number is positive and it has the absolute value symbol next to it then it is positive. If the number is negative than it become positive. With that say, we can began to solve our linear equation.

We shoudl first isolate the variable so let's subtract the number 8 from BOTH SIDES. So now we should have -24=-12(k/5)

Now we will use the disributive property. this will give us:

-24=(-12k/5)

BUT WAIT!! THE ABSOLUTE VALUE RULE MUST BE APPLIED!!

Therefore it should be -24=12k/5

Now we can just solve this regularly:

Keep reading if you don't know how to solves linear equations.

Multiply 5 to both sides:

-120=12k

k=-10

Simplify the irrational number 128; then estimate it to two decimal places.
Sergio [31]
^^^^^Simplify



Estimate
Step 1: Estimate the square root of 2:
1.4x1.4=1.96
1.41x1.41=1.9881
1.42x1.42=2.0164
1.9881 is closer to 2 than 2.0164
Square root of 2 is about 1.41

Step 2: Multiply the answer in step 1 by 8
1.41x8=11.28

8 times square of 2 is about 11.28
Square root of 128 is about 11.28

If you put square root of 128 in a calculator it would say 11.31 something...
