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.

In the diagram, gef and hef are congruent. what is the value of x

Mr. murray wants to create 100 ounces of a mixture that is 62% pecans, 30% almonds, and 8% walnuts. how will the amount of mixture a compare to the amounts of mixtures b and c that mr. murray uses? he will use half as much of mixture a as he will use of mixtures b and c combined.he will use one-quarter as much of mixture a as he will use of mixtures b and c combined.he will use one-fifth as much of mixture a as he will use of mixtures b and c combined.he will use twice as much of mixture a as he will use of mixtures b and c combined.
