Melanie buys 2 shells for $0.80. Rosi buys 3 shells for $1.20. Carlos buys 4 shells for $1.60. Use the graph to represent this situation. Is there a proportional relationship between the cost and the number of shells? If so, what does the constant of proportionality mean in this situation?

Solve 13 + w/7= -18 (w/7 is a fraction)

First work with stencil one. use a combination of reflections, rotations, and translations to see whether stencil one will overlap with the original pattern. list the sequence of rigid transformations you used in your attempt, noting the type of transformation, the direction, the coordinates, and the displacement in
