Question: Sara and Joe have a combined height of 120 inches. Joe is 6 inches more than double Sara's height. How tall is Joe?
Answer: Step-by-step reasoning process: Let x be Sara's height in inches. Joe is 6 + 2x inches tall. 120 = x + (6 + 2x). 120 = 3x + 6. 114 = 3x. x = 38 inches. Joe is 6 + 2(38) = 82 inches.
So the answer is 82.

Question: Pulsar, the shuffle-dancing bear, Polly, the pink prancing poodle, and Petra, the proud portly pachyderm, are entertainers at the Big Top Circus. In one show, Pulsar stands on his two back legs for a total of 10 minutes. Then, Polly stands on her back legs for three times as long as Pulsar.
