explanation: A is number 3 because as said in A the tram already has 5 people which is what we start with a1 = 5 and we add 11 at each stop as shown in the equation.
B is number 2 for the same reason as it started with 2 but added 4 inches of rain each time.
We have x + y = 140 degrees and x = 5y - 13 ; Then, 5y - 13 + y = 140; 6y - 13 = 140; 6y = 153; y = 153 ÷ 6; y = 25.5 degrees; x = 140 - 25.5; x = 114.5 degrees;
