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 2 add 9, then divide by 2 subtract 9, then divide by 2 For the equation, 4(3x - 12) = -3(6 + 3x), which is the correct second step? 7x - 12 = -18 - 9x 12x = -18 - 9x + 12 12x - 12 = -18 + 3x 12x - 48 = -18 - 9x The perimeter of the shown rectangle is 202 m. Which equation represents its perimeter? 2(10x + 72) = 202 12x + 72 - 2x = 204 6x + 36 - x = 101 12x(72 - 2x) = 202 72 - 2x 12x 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 items 28 items 600 items 100 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 = 240 Write a number only in the box. 3h - 4 12 What is the solution to the equation, Write a value only in the box. 5x 3 -5 = 10 ? |
