To evaluate the expression 3b - ac when a = -2, b = 3, and c = 0.5, we substitute the given values into the expression and perform the calculations:

3(3) - (-2)(0.5)

= 9 - (-1)

= 9 + 1

= 10

Therefore, the value of the expression 3b - ac when a = -2, b = 3, and c = 0.5 is 10.

To evaluate the expression 5x^2 + 2y when x = -3 and y = 0.25, we substitute the given values into the expression and perform the calculations:

5(-3)^2 + 2(0.25)

= 5(9) + 0.5

= 45 + 0.5

= 45.5

Therefore, the value of the expression 5x^2 + 2y when x = -3 and y = 0.25 is 45.5.

To evaluate the expression (3mn) / (-2p) when m = 1/3, n = -3, and p = 3, we substitute the given values into the expression and perform the calculations:

(3 * (1/3) * (-3)) / (-2 * 3)

= (-1 * -3) / (-6)

= 3 / (-6)

= -0.5

Therefore, the value of the expression (3mn) / (-2p) when m = 1/3, n = -3, and p = 3 is -0.5.

To simplify 12(x + 4), we can distribute the 12 to both terms inside the parentheses:

12 * x + 12 * 4

This simplifies to:

12x + 48

Therefore, the simplified form of 12(x + 4) is 12x + 48.

To simplify -2(2x - 5), we can distribute the -2 to both terms inside the parentheses:

-2 * 2x - 2 * (-5)

This simplifies to:

-4x + 10

Therefore, the simplified form of -2(2x - 5) is -4x + 10.

To simplify 1/2 (6x + 10), we can distribute the 1/2 to both terms inside the parentheses:

(1/2) * 6x + (1/2) * 10

This simplifies to:

(6/2)x + 5

Simplifying further:

3x + 5

Therefore, the simplified form of 1/2 (6x + 10) is 3x + 5.

To simplify 3(8 - 5x) + 2, we can distribute the 3 to the terms inside the parentheses:

3 * 8 - 3 * 5x + 2

This simplifies to:

24 - 15x + 2

Combining like terms:

-15x + 26

Therefore, the simplified form of 3(8 - 5x) + 2 is -15x + 26.

To simplify 3(8 - 5x) + 2x, we can distribute the 3 to the terms inside the parentheses:

3 * 8 - 3 * 5x + 2x

This simplifies to:

24 - 15x + 2x

Combining like terms:

-13x + 24

Therefore, the simplified form of 3(8 - 5x) + 2x is -13x + 24.

To simplify 5x - 4(2 + 3x), we can distribute the -4 to the terms inside the parentheses:

5x - 4 * 2 - 4 * 3x

This simplifies to:

5x - 8 - 12x

Combining like terms:

-7x - 8

Therefore, the simplified form of 5x - 4(2 + 3x) is -7x - 8.
