First you have to find 1/3 of the marbles. That means in the twelve marvels she has, there are three even groups. Divide twelve by three and you get four. So if each group is four, it is simple from here on out. If she started out with twelve and she lost 1/3 of them(4) it would be 12-4. You know this because lost is another for for subtract. 12-4=8. She has 8 marbles left.

Answer: Jacqueline has 8 marbles left.

Step-by-step explanation: Its pretty much just asking you how much marbles she has left if she lost 1/3. So you would find 1/3 of 12 which is 4(this is how much marbles she lost but you are trying to figure out how much she has left). So she started with 12, she lost 4, so 12-4 = 8. *To find 1/3 of 12 you can make boxes and demonstrate/shade 1/3 of 12 or you can just do 1/3 and 12/1 cross simplify which would be divided 3 by 3 and divided 12 by 3 so you would get 1/1 and 4/1 which when multiplied would be 4/1 which=4. Hope this helped!

Answer:

Greatest Common Factor: integer or variable multiplied by other integers or variables that creat a resultin product. factor x factor = product

difference of squares binomial: an expression where two perfect square terms are being subtracteda² - b² = (a+b)(a-b)quadratic: from "quad" meaning square, because the variable gets squared (like x2).

discriminant: tells you about the roots of a quadratic

general form: y = a(x - h)^2 + kstandard form: ax^2 + bx + c = 0root: a solution of an equation

zero: a value that gives you 0 for a function

x-intercept: where the graph crosses the x-axis

y-intercept: where the graph crosses the y-axis

extraneous: a solution that does not work

parabola: the graph of a quadratic

vertex: the turning point of the parabola

axis: line of reflection

translation: movement up/down and left/right of any parabola from standard position (f(x) = x2)
