Question

If p and q vary inversely and p is 26 when q is 9, determine q when p is equal to 18.

Answer 1

Answer:

• q = 13

Step-by-step explanation:

p and q vary inversely:

• p = k/q

If p = 26, q = 9, find k:

• 26 = k/9
• k = 26*9 = 234

The equation is:

• p = 234/q

When p = 18, q is:

• 18 = 234/q
• q = 234/18
• q = 13
