D 1.5

Answer 3

To solve the equation 2(2x+3)=8 for x, we can start by distributing the 2 to the terms inside the parentheses:

4x + 6 = 8

Next, we can subtract 6 from both sides of the equation:

4x = 8 - 6
4x = 2

Finally, we can divide both sides of the equation by 4 to solve for x:

x = 2/4
x = 1/2
x = 0.5

Therefore, the solution to the equation is x = 0.5.

The correct answer is A) 0.5.
