Given make v the subject of the formula.
Given make x as the subject of the formula.
Find the value of 'f', f = uv/u +v if u = 12cm & v = 4cm
48cm
16cm
3cm
12cm
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
The rule that the Perimeter (P ) of a rectangle is thrice the sum of its length (l ) and breadth (b ) is given by the formula _______.
P = 2 (l b )
P = ( l + b )
P = 3( l + b )
None of these

Frame a formula " The product of 3 consecutive numbers ( the smallest being x) is 310.
x × ( x + 1) × (x + 3) = 310
x × (x + 2) × (x + 4) = 310
x × (x + 1) × (x + 5) = 310
(x + 1) × (x + 3) × (x + 5) = 310
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
A number decreased by 15 is 35.Derive the formula.
x - 15 = 35
15 - x = 35
35 - 15 = x
x -35 = 15
