In which situation do the quantities combine to make 0? Explain your reasoning. Show the equations for each situation. 1. Emily ran 3 miles on Saturday and walked 3 miles on Sunday. 2. Beverly bought a chair for $350 and sold it 3 years later for $350. 3. Josh ran 2 laps counterclockwise around a track and then 2 laps clockwise around the track. 4. Trey deposited $150 into his savings account on Friday and withdrew $100 the following week.
1. 3 + 3 = 6 2. -350 + 350 = 0 <--- CORRECT 3. 2 + 2 = 4 4. 150 + (-100) = 50

Which multiplication equation is FALSE? You must explain each choice. A. (-a) · 0 = 0 B. (-a) · 1 = (-a) C. (-a) · (-1) = (-a) D. (-a) · b = b · (-a)
A. True because anything times 0 = 0 B True because a negative numbers times 1 = that negative number C. False because (-)(-) = (+). Same signs = + number D. True because (-)(+) = (-) and (+)(-) = -. Or substituting in numbers can help.
