Agroup of 2 adults and 4 children spent $38 on tickets to a museum. a group of 3 adults and 3 children spent $40.50 on tickets to the museum. based on this information, how much is an adult ticket, and how much is a child ticket? 2a + 4c = 38.00 3a + 3c = 40.50 what values of a and c represent the solution to the system? a = c =

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.

What expression is equivalent to (2x-1)(x-3)?

3x + 4y = 5 x- 3y = -7 solve by substitution
