The correct line to convert a string into a numerical value is

Create a variable called z, assign x + y to it, and display the result in an alert box. The correct expression is...

  var y = 10

  var z = x -y

  prompt (alert (x-y)

• var x = 5

  var y = 10

  var z = x + y

  alert (x + y)

• var x = 5

  var y = 10

  var z = x + y

  alert (z)

  alert ("Hello World")}

• if x > y (

  alert ("Hello World"))

observe the following exercise:
