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.
