Sarah spent $15.75 at the movies on a ticket and snacks. Then she earn $40 babysitting and bought a book for $9.50. Sarah has $34.75 left. Which integers would you use to represent the dollar amounts described in the situation?

Find the equation of the line with slope =8 and passing through (6,53) write your equation in the form y=mx+b

If the discriminant if a quadratic equation is 4 which statement describes the roots?

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.
