I need help!! I’m trying to find the value of P

Question

If p varies inversely as q, and p=2 when q=6, find p when q=3.

p=

Answer 1

If p and q vary inversely then their product is constant so to start p x q =12 so

when p= 3 3q must = 12

Therefore q is 4

Answer 2

If p varies inversely as q, and p=2 when q=6, find p when q=3.

first equation will be p= n/q

next: input p=2, q=6

2=n/6

Multiply both sides by 6

n=6*2= 12

recall first equation p=n/q

input q=3, n=12

p=12/3

p=4

If p varies inversely as q, and p=2 when q=6, find p when q=3.

As p varies inversely to q

p= K/q

given p=2 when q=6

So

p=K/q gives

2= K/6

Cross multiplying

gives K =12

So

p= 12/q

Now for q=3

p= 12/3 , gives p=4
