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

Nikitich [7]

Answer:

with T = 50⁰C, we have:

50 = 200 - 5x - x²

<=> x² + 5x = 150

<=> x² + 5x - 150 = 0

=> x = 10
