Question: A student took a test composed of 20 question, with correct answers worth 2 points. If the student received 34 points for his grade, how many questions were correct?
I KNOW THE ANSWER IS 17 BUT PLEASE PUT IN AN EQUATION FORM
ex: (20x2)-34 = ???????
let x = number of questions answered correctly
set up the equation:
2x = 34
2x = 34 *divide both sides by 2 to get x
x = 34/2 = 17
so there,, :)
