Without multiplying determine the sign of the product (-468,256)(183,758).​

Which rational number could be graphed between -4 and -5

How much dextrose 70% must be mixed with dextrose 5% to prepare 1,000 ml of dextrose 20%?

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.
