Mathematics 2010 JAMB Past Questions - Question 13: Make Q the subject of the formula if P=M/5(X+Q)+1
A:
B:
C:
D:
Correct Answer
B
Explanation
P = M/5(x+Q)+1P-1 = M/5 (X+Q)5/M (P-1) = X + Q5/M (P-1) -X = Qtherefore Q = 5(p-1)-MX / M = 5P -5-MX /M = 5P -MX -5 /MTo make Q the subject of the formula P = M/5(X + Q) + 1, we can follow these steps:1. Start by subtracting 1 from both sides of the equation to isolate the term M/5(X + Q) on the right side: P - 1 = M/5(X + Q)2. Multiply both sides of the equation by 5 to eliminate the fraction: 5(P - 1) = M(X + Q)3. Distribute the 5 on the left side: 5P - 5 = MX + MQ4. Rearrange the equation to isolate the term MQ: MQ = 5P - 5 - MX5. Finally, divide both sides of the equation by M to solve for Q: Q = (5P - 5 - MX) / MTherefore, Q is the subject of the formula when expressed as Q = (5P - 5 - MX) / M.
