Identify the number property. 1. 3x + 5 = 5 + 3x 2. 6 * (7 * 8) = (6 * 7) * 8 3. 9 + (6x + 11) = (6x + 11) + 9 4. if 7 = x, then x = 7 5. if x = 4 and 4 = y, then x = y 6. every real number is equal to itself name the property that justifies each step 1. (2* 93) * 5 = (93 * 2) * 5 = 93* (2 5) = 93 * 10 = 930 2. (26 + 71) + 14 = 26 + (71 + 14) = 26 + (14 + 71) = (26 + 14) + 71 = 40 + 71 = 111 3. 50 * (47 * 8) = 50 * (8 * 47) = (50 * 8)* 47 = 400 * 47 = (100 *4) * 47 = 100 * (4 * 47) = 100 * 188 = 18,800 4. [13 + 3] + (-3) = 13 + [3 + (-3)] = 13 + 0 =13 5. (17 * 5) * 1/5 = 17 * (5 * 1/5) = 17 * 1 = 17
