include 2 pairs of brackets to make this equal to 3

When only separate discreet points are graphed it is called?

1.two more than the quotient of a number and 6 is equal to 7 use the c for the unknown number translate the sentence into an equation

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.
