\text{Subtract both sides by -20x}\\\\-2x+50=+30\\\\\text{Subtract both sides by 50}\\\\-2x=-20\\\\\text{Divide by -2}\\\\\large\boxed{x=10}\\\\\text{They're the same price at 10 hours}\\\\\text{I hope this helps!}\\\text{Best regards,}\\\text{MasterInvestor}

Please help I need this done by tomorrow
melomori [17]

Answer:

n = 9

Step-by-step explanation:

We require to consider \sqrt{n+16}

For it to be a natural number then it must be a perfect square

If n = 9 , then

\sqrt{9+16} = \sqrt{25} = 5

and

\frac{n}{3} = \frac{9}{3} = 3

34 + n = 34 + 9 = 43

5, 3, 43 ∈ natural numbers

Then n = 9 is the smallest value
