Answer:
b =
Step-by-step explanation:
Given
a = ( multiply both sides by 3b - 2 )
a(3b - 2) = b + 1 ← distribute left side
3ab - 2a = b + 1 ( subtract b from both sides )
3ab - b - 2a = 1 ( add 2a to both sides )
3ab - b = 1 + 2a ← factor out b from each term on the left side
b(3a - 1) = 1 + 2a ( divide both sides by 3a - 1 )
b =
Answer:
r=C/2π
Step-by-step explanation:
here we just have to rearrange the given formulae in such a way that it finds out the value of r.
Given formulae is C=2πr
we can carry 2π to the left hand side.
r= . is the recquired formulae.
