3. To improve in skating, Kara's coach told her that she needs to take two times as jumps
and four times as many spins every day. Ifj represents the number of jumps and s
represents the number of spins Kara does daily, write an expression to show how many
spins she will need to take in order to improve in skating.

among the four of them. Sandra also paid a $8 tip. How much did Sandra pay in
total? Write your answer as an expression.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
