Drake estimates that he can finish 12 math problems in 45 minutes. How many hours will
it take to complete 24 math problems?

Please show work.

1.5 hours

Step-by-step

If it takes him 45 minutes to do 12 questions it would take him double the time to do 24

It will take him 1 hour and 30 minutes, or 1 and a half hours to finish 24 math problems. Another solution could be 1.5 hours!

Step-by-step explanation: We know he can finish 12 math problems in 45 minutes.

To find how many minutes it takes him to complete 24 math problems, simply multiply, 12 x 2 and 45 x 2.

12 x 2 = 24 total math problems.

45 x 2 = 90 Minutes.

90 minutes can also be written as 1 hour and 30 minutes, or 1 and a half hours. That is your answer!

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
