User: 16. For a button to fit through its buttonhole, the hole needs to be the size of the button's diameter. What size buttonhole is needed for a button with a circumference of 7.38 centimeters? (Use the value of 3.14 to represent pi.) A. 3.69 centimeters B. 5.14 centimeters C. 2.35 centimeters D. 1.14 centimeters

Weegy: 2.35 centimeters is the size of the buttonhole that is needed for a button with a circumference of 7.38 centimeters. ***C = d Thus, d = C / = 7.38 / 3.14 = 2.350, which makes 2.35. We should use 3.14 as 's value and not 3.1415. 2.35 centimeters

If 3 times a number minus 2 equals 13, the number is 5 .
If the number is x
3x - 2 = 13
3x = 13 + 2
3x = 15
x = 15/3
x = 5
