Solving Equations - how to??
 Given the equation, 2x - 9 = 19, what two steps would you do to isolate the "x"?subtract 9, then multiply by 2 add 9, then multiply by 2add 9, then divide by 2subtract 9, then divide by 2 For the equation, 4(3x - 12) = -3(6 + 3x), which is the correct second step? 7x - 12 = -18 - 9x12x = -18 - 9x + 1212x - 12 = -18 + 3x12x - 48 = -18 - 9x The perimeter of the shown rectangle is 202 m. Which equation represents its perimeter?2(10x + 72) = 20212x + 72 - 2x = 2046x + 36 - x = 10112x(72 - 2x) = 20272 - 2x12x The cost of manufacturing plastic packaging is C = 10 + 5n (where "C" is the cost in cents and "n" is the number of items). If the cost is 130 cents, how many items were manufactured?  24 items28 items600 items100 items Paula works at a clothing store. Her weekly pay is modeled by the relation, P = 600 + 0.05s, where "P" is her pay and "s" is the value of clothing she sold. One week she earned \$1,000. What value of clothing did she sell that week?Write the number only (no comma or \$)  What is the value of "h" for this relationship? AREA = 240Write a number only in the box.3h - 412 What is the solution to the equation, Write a value only in the box.5x3-5=10?
