Question

p is inversely propotional to Q,P=9 when Q=2,value of P =? when Q =3​

P is inversely proportional to to Q, so it is directly proportional to 1/Q.

With k as an unknown, then: P=k/Q or PQ=k

P=x when Q=3, so x=k/3. When Q=x, P=k/x.

Next, simplify the two equations for the same variable.

Technically, this is one of many techniques for solving a system of two equations with two unknowns.

x=k/3 and P=k/x become

k=3x and k=Px

Px = 3x. Divide both sides by x to produce

P=3

Answer 2

p is inversely propotional to Q,P=9 when Q=2,value of P =? when Q =3

Px = 3x. Divide both sides by x to produce

P=3
