Daria used fraction
tiles to show that 3/5 is equivalent to 6/10. Compare the
number and size of fraction tiles needed to model each fraction.

6x - 8 = 16 solve the following equation. then place the correct number in the box provided.

Explain how you can use the associative property to evaluate (7x50)x4.

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.
