To find unit rate for all 24 problems.  
12 problems completed in 1 hour = 12 in 60 minutes
 Last 12 problems in 3 hours = 12 in 180 minutes
 Total 24 in (180+60= 240) minutes
 Time taken to solve one problem = 240/24 = 10 minutes. 
 This means Deandra on an average took 10 minutes to solve each problem.

If you divide 12 by 3 the correct answer should be 4 problems per hour.

Determine whether f(x)=5x+1/x and g(x)= x/5x+1 are inverse functions. Explain how you know.
vladimir1956 [14]
A property of inverse functions is that if f(x) = a, g(a) = x

F(x) = (5x+1)/x
G(x) = x/(5x+1)

Plug in x = 3.
F(3) = 16/3
G(16/3) = 16/83. Since it doesn’t equal 3, it’s not an inverse function
