Elijah buys a jersey that costs $56.00. his bank account balance is now -$6.50. which math sentence describes how much he owes?

a. > $7.00
b. > $6.00.
c. > -$6.00
d. > -$7.00

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.
