\( \frac{a^{2}-3 b-4 c}{a b c} \quad \) per \( a=-\frac{1}{3} \quad: \quad b=\frac{1}{2} \quad, \quad c=-\frac{1}{4} \)

Solving Systems of Equations Exit Ticket 1. Mindy's high school class has a total of 150 students and they are planning a field trip. The school has smal buses and vans to transport all students. Each van can seat 8 students and each bus can seat 14 students. Ther are only 15 drivers, so the total number of vehicles that they can take must be 15 . How many of each vehicle will Mindy's class need to transport everyone?

1)) Select the expressions that are equivalent to \( 2(4 k) \),

\( a^{3}+3 a b^{2}-3 a^{2} b-b^{3} \) entre \( a-b \)

Factor completely: \[ 2 w^{3}-2 w^{3} x^{4} \]

Solve for \( x \) \[ y-\frac{5}{x}=\frac{3}{v} \]
