t = d/s
t = s/d
t = sd
t = d2 s

Frame a formula for " A number x multiplied by itself is 25 more than the number".
2x2 = 25
2x2 + x = 25
x2 = x + 25
x2 + 25 = x
If A = π r2 find A when r = 14 cm and π = 22/7 ?
516 cm2
616 cm2

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
