### Subject: Writing

How do you compose an introduction for an informative or opinion based paper?

The first thing to think about it is what are you trying to teach or say? Are you trying to inform someone about a topic, or persuade someone of your opinion? Some ideas to start the paragraph is to start with a thought-provoking question or an interesting fact that leads to the topic sentence. Then let that lead into the topic sentence or thesis, this should include some of the points of your paper, such as the supporting points of your opinion. Lastly, add a transition that leads to the paper or the second paragraph.

### Subject: Pre-Algebra

Do the addition or subtraction -987 - - 654 =

The best way to think of this is putting parenthesis around the -64, which makes the equation look like. -987 - (-654). The important rule to remember is that two negatives equal a positive, so the subtraction of -654 equals a positive 654. -987 + 654 Then add as usual remembering that the first number is negative plus a 654 so the numbers will become a smaller number. -987 + 654 = -333

Solve the Equation: 5(-3x-2)-(x-3) = -4(4x+5) +13

The solving of the equation means that for this equation we are solving for x that both sides will be equal to each other. First, let's focus on the left-hand side of the equal sign. The first thing we should do is distribute the 5 to (-3x-2). 5 times -3x = -15x. 5 times -2 = -10. After we distribute the 5, it should come out to (-15x-10). Now on the left hand side we have, (-15x - 10) - (x-3). Combine like terms on this side being sure to pay attention to the subtraction of the (x-3). Combine the like terms of -15x - x, which equals -16x. Then combine the like terms without the variable which is ( -10 - (-3)) = -7. After combining like terms, on the left side, the result is, -16x -7. We will do the same with the right-hand side of the equation, starting with the distribution of the -4 to the (4x+5), which equals -16x-20. Then we can combine like terms, which are only the terms without a variable on this side, combine -20 +13 = -7. The result on the right-hand side was -16x -7. The equation now looks like -16x -7 = -16x -7. Then take the 16x and add it to both sides and add the 7 to both sides resulting in 0 =0 which is true.
