If 2(x + 5) = 12.5, what is the value of 4x?

To solve the equation, let's simplify both sides:

2(x + 5) = 12.5

First, distribute the 2 to both terms inside the parentheses:

2x + 10 = 12.5

Next, subtract 10 from both sides to isolate the variable:

2x = 12.5 - 10
2x = 2.5

Finally, divide both sides by 2 to solve for x:

x = 2.5 / 2
x = 1.25

To find the value of 4x, we multiply x by 4:

4x = 4 * 1.25
4x = 5

So the value of 4x is 5.
