Plz 1. mrs. smith's class is going on a field trip. the cost of the trip is $26. this includes the price for lunch, which is $12 and the cost of 2 tickets. which equation shows you the cost of 1 ticket? t + 12 = 26 2t - 12 = 26 2t + 12 = 26 12t + 2 = 26 2. 5(b + 6) = 18 9.6 -2.4 2.4 3.6 3. 1/2(6g + 2) = 12 3.33 1.67 3.67 4.3 4. 17 + r/3 = 28 33 135 4.94 3.67 5. 28 - 2(5a - 3) = 47 8.1 -2.5 1.3 -1.3
