Answer:
x =(5/3)
Step-by-step explanation:
The given expression is 
Now to simplify it,
The first step is to cross multiply.
So, the expression becomes

or, -1 = 3x - 6
⇒ 3x = -1 + 6
⇒ 3x = 5 , or x =(5/3)
7/8 , this is because there will only be 7/8 left over , hope this helps :)
Answer:
8 Joule
Step-by-step explanation:
Mass of block = 2 kg
Displacement = x = 800 mm = 0.8 m
Spring constant = k = 25 N/m
Potential Energy of a spring
Work done = Difference in Potential Energy
Work Done = Δ P.E.

⇒P.E. = 0.5×25×0.8²
⇒P.E. = 8 Nm = 8 Joule
Here already the spring constant and displacement is given so the mass will not be used while calculating the potential energy.
It would be 30/48 but you still have to simplify it
5/8 is the answer
