Which of the following statements describes a correct method for solving the equation below? 20 + 2w = 50 a) add 20 to both sides of the equation, and then divide both sides by 2. b) subtract 20 from both sides of the equation, and then divide both sides by 2. c) divide both sides of the equation by 2, and then add 20 to both sides. d) divide both sides of the equation by 2, and then subtract 20 from both sides.

You are trying to solve for "w", to do so you:

20 + 2w = 50     Subtract 20 on both sides  

2w = 30  Divide 2 on both sides to get "w" by itself

w = 15

Your answer is B

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
