First try was incorrect My friend Elentire bought some lirns for $2 each and some pisquets for $4 each. The total cost was about $176. Altogether, she bought 66 items. Write a system of equations, in standard form, modeling the relationship between lirns (x) and pisquets (y). ​

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.
