Answer:
38 pages per hour
Step-by-step explanation:
Rate of reading = 
By substituting the given values in the question,
Total number of pages read by Davida =
= 
Time taken by Davida = 45 minutes
Since, 1 minute =
hours
Therefore, 45 minutes =
hours
Rate of reading = 
= 
= 38 pages per hour
Therefore, rate of reading by Davida is 38 pages per hour.
Answer:
Elena's move will lead to the solution of the problem
Step-by-step explanation:
To solve the equation 7.5d=2.5d, Lin divides each side by 2.5d, and Elena subtracts 2.5d from each side. Will both moves lead to the solution? Explain your reasoning
Given:
7.5d = 2.5d
Lin divides each side by 2.5d, Lin:
7.5d / 2.5d = 2.5d / 2.5d
3 = 1
This can not be the solution to the problem because 3 can not be Equal to 1
Elena subtracts 2.5d from each side
7.5d = 2.5d
7.5d - 2.5d = 2.5d - 2.5d
5d = 0
This can lead to the solution of the problem
Elena's move will lead to the solution of the problem
