In worksheet on changing the subject of a formula we need to change the subject of the formula is a variable which is expressed in terms of other variables involved in the formula.
(a) A = l × b
make b as subject
(b) L = C.P. – S.P.
make S.P. as subject
(c) V = u + ft
make t as subject
(d) S = D/T
make D as subject
(e) V = πr²h
make r as subject
(f) C = 2πr
make r as subject
(g) P = 2 (l + b)
make l as subject
(h) S = n/2 (a + l)
make a as subject
(i) A = P {1 + (Rn/100)}
make n as subject
(j) 1/x = y + z/y + 1
make y as subject
(k) y = mx + c
make x as subject
(l) D = b² - 4ac
make c as subject
(m) T = 2π √(l/g)
make g as subject
(n) S = ut + 1/2 gt²
make g as subject
(o) C = 2πr (h + r)
make h as subject
(p) h² = p² + b²
make b as subject
(q) S.P. = {(100 + G%) C.P.}/100
make C.P. as subject
(r) HM = 2ab/(a + b)
make a as subject
(s) I = (P × R × T)/100
make R as subject
(t) A = 1/2 (l₁ + l₂) h
make l₂ as subject
