Answer 1

Ответ:

Пошаговое объяснение:

1)7a+8b

2)11b

3)50y

4)51a

Answer 2

Let's simplify each of the given expressions:

1. 7a + 8b

   • There's no common factor between 'a' and 'b,' so you can't simplify this further. The expression remains as is: 7a + 8b.

2. 16b - 5b

   • These both contain 'b' as a common factor. Subtracting 5b from 16b leaves you with 11b: 16b - 5b = 11b.

3. 46y - 18y + 22y

   • Combine like terms. Here, you have 'y' as a common factor. Add the coefficients together: 46y - 18y + 22y = (46 - 18 + 22)y = 50y.

4. 12a + 13a + 26a

   • Again, combine like terms. Here, you have 'a' as a common factor. Add the coefficients together: 12a + 13a + 26a = (12 + 13 + 26)a = 51a.

So, after simplifying each expression:

1. 7a + 8b remains as 7a + 8b.
2. 16b - 5b simplifies to 11b.
3. 46y - 18y + 22y simplifies to 50y.
4. 12a + 13a + 26a simplifies to 51a.
