Given make v the subject of the formula.
Frame a formula for 1/5th of number x is 3 less than 20.
5x = 20 -3
5x = 3 - 20
x/5 = 20 - 3
x/5 = 3 - 20
Obtain the formula fort the statement : when thrice a certain number is subtracted from 64, the result is 28.
2 - 3 x = 64
64 - 3 x = 28
28 = 3x + 64
None of these

In formula P = 2 (l x b ), make l the subject.
l = 2b - p/2
l = 2 -2b/p
l = p - 2/2b
l= p - 2b/2
Given v2 = u2 - 2ft,make t subject of the formula.
t = 2f (u2 - v2)
t = 2f (u2 + v2)
