The solution of |3x + 12| = 18 is -10 or 2. true false there is no solution for the absolute value inequality |2x - 4 | ≥ - 10 true false what is the solution of |x - 10| = 4? . -6 or -14 -6 or 14 6 or 14 6 or -14 rearrange the formula, d=rt , to solve for r in terms of d and t. r = dt r = d/t r= t/d t = d/r

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
