The owner of a bike shop sells tricycles (3 wheels) and bicycles (2 wheels), keeping inventory by counting seats and wheels. one day she counts 13 seats and 31 wheels. how many of each type of cycle are there? a. t + b = 13 3t + 2b = 31 b. t + b = 5 3t + 2b = 44 c. t • b = 44 3t + 2b = 13 d. t + b = 31 3t + 2b = 13

Write two subtraction equations that are equivalent to 5 + 12 = 17.

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.
