4a+1,6b+0,8c

Answer 2

To simplify the given expressions, let's perform the calculations step by step:

1. (4а - 3в - 0.8) * 2: Multiply each term inside the parentheses by 2: 4а * 2 - 3в * 2 - 0.8 * 2 Simplifying further: 8а - 6в - 1.6

2. 1.5 * (-2.4а + 3.8в - 0.1с): Multiply 1.5 with each term inside the parentheses: 1.5 * (-2.4а) + 1.5 * (3.8в) + 1.5 * (-0.1с) Simplifying further: -3.6а + 5.7в - 0.15с

3. (-2а + 6в - 0.008) * (-3): Multiply each term inside the parentheses by -3: -2а * (-3) + 6в * (-3) - 0.008 * (-3) Simplifying further: 6а - 18в + 0.024

4. (-2.5а - в - 0.5с) * (-1.6): Multiply each term inside the parentheses by -1.6: -2.5а * (-1.6) - в * (-1.6) - 0.5с * (-1.6) Simplifying further: 4а + 1.6в + 0.8с

Therefore, the simplified expressions are:

1. (4а - 3в - 0.8) * 2 simplifies to 8а - 6в - 1.6.
2. 1.5 * (-2.4а + 3.8в - 0.1с) simplifies to -3.6а + 5.7в - 0.15с.
3. (-2а + 6в - 0.008) * (-3) simplifies to 6а - 18в + 0.024.
4. (-2.5а - в - 0.5с) * (-1.6) simplifies to 4а + 1.6в + 0.8с.
