Answer 3

Sure! I can help you simplify these expressions. Let's go through each one:

11. -8(2 - 2y) + 4(3 - 4y)

Apply the distributive property: -8 * 2 + 8 * 2y + 4 * 3 - 4 * 4y

Simplify: -16 + 16y + 12 - 16y

Combine like terms: (-16 + 12) + (16y - 16y)

Simplify further: -4 + 0

Final result: -4

12. (3x - 11) * 2 - 5 * (4 - 3x)

Apply the distributive property: 6x - 22 - 20 + 15x

Combine like terms: 6x + 15x - 22 - 20

Simplify further: 21x - 42

Final result: 21x - 42

13. (82 - 1) * (-6) + (3a - 7) * (-2)

Simplify inside the parentheses: 81 * (-6) + (3a - 7) * (-2)

Multiply: -486 + (-6) * (3a - 7)

Apply the distributive property: -486 + (-6 * 3a + (-6) * (-7))

Simplify further: -486 + (-18a + 42)

Combine like terms: -486 - 18a + 42

Final result: -18a - 444

14. -0.5(-2x + 4) - (10 - x)

Apply the distributive property: 1x - 2 + 10 - x

Combine like terms: (1x - x) + (-2 + 10)

Simplify further: 0x + 8

Final result: 8
