solving the following system \[ \left\{\begin{array}{l}x+y=51 \\ 5 x+10 y=425\end{array}\right. \]

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

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

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?

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

\( 2 x-5=4 \) \( \alpha x+10 y=4 \), se satisfaga: \( \quad \forall x \quad R^{+} y \forall y \quad R \)
