Answer 2

Problem Analysis

Two brothers, Andrei and his brother, collect stamps. Andrei has collected 70 stamps, which is 10 stamps less than his brother. They want to know if they can fit all their stamps in an album that has space for 140 stamps.

Solution

To determine if Andrei and his brother can fit all their stamps in the album, we need to calculate the total number of stamps they have.

Let's assume Andrei's brother has x stamps. According to the given information, Andrei has collected 10 stamps less than his brother. Therefore, Andrei has x - 10 stamps.

The total number of stamps they have is the sum of Andrei's stamps and his brother's stamps:

Total stamps = Andrei's stamps + Brother's stamps Total stamps = (x - 10) + x Total stamps = 2x - 10

Now, we can check if the total number of stamps is less than or equal to 140. If it is, then they can fit all their stamps in the album.

Calculation

Let's calculate the total number of stamps they have:

Total stamps = 2x - 10

Since we don't have the exact value of x, we cannot calculate the exact total number of stamps. However, we can determine the conditions under which they can fit all their stamps in the album.

If the total number of stamps is less than or equal to 140, they can fit all their stamps in the album.

2x - 10 ≤ 140

Now, let's solve this inequality to find the range of values for x:

2x ≤ 150 x ≤ 75

Therefore, if Andrei's brother has 75 or fewer stamps, they can fit all their stamps in the album.

Answer

If Andrei's brother has 75 or fewer stamps, they can fit all their stamps in the album that has space for 140 stamps.

Note: The exact number of stamps Andrei's brother has is not provided, so we can only determine the range of values for which they can fit all their stamps in the album.
