Q: If you can, use slacks and a collared, button-up shirt. The Hogwarts dress code requires everyone to look smashing. Wear a burgundy cardigan (red sweater) in cold weather. Harry Potter doesn't wear this all the time in the films, but it's required for all Hogwarts students in the books. Besides, a shirt and trousers aren't too wizardly by themselves. There are several ways to track one of these down: Ask whether they have old ones they will sell cheaply for costume purposes.  Thrift stores, charity stores, and costume shops might stock these. If you know any professors, judges, or lawyers, ask to borrow their robes. (Note – lawyers in the United States don't wear robes.) Wear a long, black coat back-to-front, or a long black skirt over your shoulders. A pointy black hat isn't necessary for Harry Potter, but it is easily recognized as a wizarding hat. The main use for a hat like this is to hide long hair, if you have it. Find a pair of round glasses with black frames at a used clothing store or drugstore. Put a piece of clear sellotape (scotch tape) over the middle of the glasses, like Harry does when his glasses break.  Toy stores sell fake glasses along with a nose and mustache. Cut off the extra bits, and they're the perfect shape. If you have your own glasses, you can make the rims black with puffy paint. For a quicker costume, cut out empty circles from black construction paper and tape them over the rims. If you're lucky, you can find a scarf with red and gold stripes at a clothing store, or have someone knit or sew it for you. Otherwise, you'll need to start with a plain red scarf. There are a couple ways you can add the golden or yellow stripes:  Wrap a yellow ribbon around the scarf in a spiral. Staple or sew it in place. Cut yellow felt or construction paper into rectangles. Lay these out on the scarf. Staple or sew them on.  Paint the fabric with fabric paint. Find a red tie from a thrift shop – you probably don't want to paint on your own or your family's. You can make this the same way you did the scarf, but fabric paint will look best. In the films, the Gryffindor ties are red with diagonal gold stripes. Draw a thin gold line. Skip 3 cm (1.2 in), then draw two thick lines with a thin gap in between. Skip another 3 cm (1.2 in), and repeat with a new thin line. Draw the famous lightning bolt running down your forehead. Use red lip liner, lipstick, or a nontoxic, washable marker. The scar is sometimes shown and described as running down the middle of his forehead, or running down the right side.
A: Put on black trousers and a white shirt. Wear an old black robe. Look in graduation stores that sell academic gowns. Hide long hair under a hat. Make a pair of "broken" glasses. Make a red and gold scarf. Make a red and gold tie. Draw the lightning bolt scar.

Q: It doesn’t matter which equation you choose, but you might want to look for one that will give you numbers that are easier to work with. For example, if your simultaneous equations are 1) x+2y=−4{\displaystyle x+2y=-4} and 2) 2x+5y=1{\displaystyle 2x+5y=1}, you will probably want to begin with the first equation, because the x{\displaystyle x} is already by itself. You could also start by isolating the y variable (or whatever other variable the equation uses). For example, if you are beginning with x+2y=−4{\displaystyle x+2y=-4}, you could solve for x{\displaystyle x} by subtracting 2y from each side.x+2y=−4{\displaystyle x+2y=-4}x=−4−2y{\displaystyle x=-4-2y} Place the value in parentheses for clarity. For example, if you found x=−4−2y{\displaystyle x=-4-2y} in the first equation, plug in −4−2y{\displaystyle -4-2y} for x{\displaystyle x} in the second equation:2x+5y=1{\displaystyle 2x+5y=1}2(−4−2y)+5y=1{\displaystyle 2(-4-2y)+5y=1} Remember to follow the order of operations. For example, to solve for y{\displaystyle y} in the equation 2(−4−2y)+5=1{\displaystyle 2(-4-2y)+5=1}, first use the distributive property to multiply.2(−4−2y)+5y=1{\displaystyle 2(-4-2y)+5y=1}−8−4y+5y=1{\displaystyle -8-4y+5y=1}−8+y=1{\displaystyle -8+y=1}y=9{\displaystyle y=9}
A: Choose the equation you want to work with first. Isolate the x{\displaystyle x} variable in the first equation. Plug in the value of x{\displaystyle x} into the second equation. Find the value of y{\displaystyle y} in the second equation.

Q: The paper should be longer than a regular sheet of paper.It needs to wrap around enough to look like a scroll. Your paper needs to be thinner than the dowels you use, so you may have to cut some off of the edges. There are many different types of paper that can be used to make a good scroll.  Two sheets of regular white paper taped together end to end Brown paper grocery bag Parchment Paper Rice paper Papyrus paper Dowels are round rods made of wood, metal, or plastic. Scrolls are typically made using wooden dowels. Dowels come in different lengths, so you might have to cut them to the right size for your paper. You want the dowels to be about 1 to 2 inches longer than the paper. The thinner the dowel, the tighter you can wind up your scroll. You can choose the thickness of the dowel you would like to use.  ⅜ inch ¼ inch ½ inch 1 inch Decide what you want the scroll to say or display on the inside. If you don't know what you want it to look like, some ideas are hieroglyphs, chinese characters, or a still life picture. Choose a method to apply your script or artwork to the scroll.  Painting Printing Coloring Calligraphy Handwritten or drawn You can assemble a scroll using one dowel at the top of the paper or two dowels on the top and bottom of the paper. Use a strong glue to secure the dowels to the edges of the paper. Press firmly and hold for a few seconds to ensure the dowel is adequately attached to the paper.  Make sure the glue extends the entire length of the edge of the paper. You can also wrap the paper around the dowel and glue it to itself. If you decide to do this method, make sure you get the paper wrapped extremely tight around the dowel so it doesn't have room to slide around. Embellishments can make the scroll look authentic and give it that extra flair. There are many ways to embellish your scroll and make it unique.  Attach a ribbon to the top for hanging. Add an ornament to the ends of each dowel, like a wooden wheel. This would be easier to do before attaching the paper onto the dowels. Use ribbon, string, or twine to tie the scroll together after rolling. There are two different ways of rolling your scroll.  If you have a one dowel scroll, roll the paper around the dowel until the entire paper is rolled. Secure the paper with a ribbon, string, or twine by tying it around the scroll. With a two dowel scroll, roll both sides of the paper around the dowels until they meet in the middle. You can also secure this type of scroll with ribbon, string, or twine.
A:
Select the paper. Choose the dowels. Create the artwork. Assemble the scroll. Embellish the scroll. Roll the scroll.
