Answer:
v - u = 10t 
t = 1/10x(v-u) 
2. 1/6 x (m - 19) = n 
3. u = d/t - at
4.- 1/6 x (A - P) 
T = 2.5
Explanation:
v = u + 10t 
v- u = 10t
divide both sides of the equation by 10 
 t = 1/10x(v-u) 
2. m = 6n + 19 
subtract 19 from both sides of the equation 
m - 19 = 6n 
divide both sides of the equation by 6
 1/6 x (m - 19) = n 
3. d = ut + at²
subtract at² from both sides of the equation 
d - at² = ut
divide both sides of the equation by t
(d/t) - at = u
4. P = A - 6D
subtract A from both sides of the equation 
P - A = -6D
divide both sides of the equation by -6
-1/6(P - A) = D
