Proportionality, assuming constant rate. 460 dives/12 hours = x dives/3 hours. Solve for x.
1/x + 1/y = 8
x + y = 8
6/x + 12/y = 72n

Step-by-step explanation:
Answer:
2 real solutions
Step-by-step explanation:
Get all the terms to one side
10n^2 = 10 - 8n
10n^2 +8n -10 =0
ax^2 +bx+c =0
The discriminant is
b^2 -4ac
8^2 - 4(10)(-10)
64 +400
464
If the discriminant is greater than 0 we have 2 real solutions
