Which statement best defines a universal law
goldenfox [79]
Answer: B. It is in effect at all times.

Explanation:
By definition, a universal law is immutable, meaning that it does not change and it is in effect at all times. 

This definition should be appled within the scope of what "universal" means.
For example, the law of "Cause and Effect" is stated in physics by Newton's third law: To every action, there is an equal and opposite reaction.  

Discussion:
Our perception of the universe is limited usually to our solar system, within a physical and material universe. We cannot be certain that our accepted universal laws apply in the same manner in a nonmaterial or spiritual universe.

How do i do this and what’s the answer????
inysia [295]

Answer:

The correct answer is z = -6.

Step-by-step explanation:

1/3 (2z + 6) = 1/4 (z - 2)

The first step I am going to take is to multiply both sides of the equation by 12 (the least common multiple of 3 and 4).  This will eliminate the fractions on both sides of the equations and make the numbers much easier to work with.

4 (2z + 6) = 3 (z - 2)

Next, we can use the distributive property to eliminate the parentheses.  This means multiplying each term inside the parentheses by the coefficient on the outside of the parentheses.

8z + 24 = 3z - 6

Now, we can subtract 3z from both sides of the equation.

5z + 24 = - 6

Next, we should subtract 24 from both sides of the equation.

5z = -30

Finally, we can divide both sides of the equation by 5.

z = -6

Therefore, the correct answer is z = -6.

Hope this helps!
