(2. An art museum has 48 paintings in one room and 31 paintings in another room. What is a reasonable estimate for the total number of paintings in these two rooms? Explain.

To find a reasonable estimate for the total number of paintings in the two rooms, we can simply add the number of paintings in each room. Given: - Number of paintings in the first room = 48 - Number of paintings in the second room = 31 To find the total number of paintings, we add the number of paintings in each room: Total number of paintings = Number of paintings in the first room + Number of paintings in the second room Let's calculate this: Calculate the value by following steps: - step0: Calculate: \(48+31\) - step1: Add the numbers: \(79\) A reasonable estimate for the total number of paintings in the two rooms is 79. This is obtained by adding the number of paintings in each room (48 + 31 = 79).
