None of these answers are correct.
\( 3 \) cars and \( 4 \) buses

Solve the system by the substitution method. Be sure to check all proposed solutions.
\( x + 5 y = 15 \)
\( 7 x + 6 y = 18\)
A ferris wheel is \( 35 \) meters in diameter and boarded from a platform that is \( 2 \) meters above the ground. The six o'clock position on the ferris wheel is level with the loading platform. The wheel completes \( 1 \) full revolution in \( 8 \) minutes. The function \( h = f ( t ) \) gives your height in meters above the ground \( t \) minutes after the wheel begins to turn.
