Shari and Ana are playing games at an arcade. Shari has $37.50 and is playing $0.50 games. Ana has $42.75 and is playing $0.75 games. Sandor wants to know when Shari and Ana will have the same amount of money remaining. So he wrote and solved this equation.

Let x = number of games played.

Equation: 37.50 – .5x = 42.75 – .75x

Step 1: 37.50 – 1.25x = 42.75

Step 2: – 1.25x = 5.25

Step 3: – 4.2 = x

Sandor knows his answer is incorrect because a negative number of games cannot be played. What was Sandor’s mistake?

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.
