Some 7th grade math I need help pls

$5.2

Step-by-step explanation:

To find 5e profit Janet made in week 2 than week 4, we find the difference between the 2 negative numbers.

But, since they are negative we do Smallest minus Largest ( It’s easier that way)

21.74-16.54 ( ignore the minuses ) = 5.2

That’s the difference.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

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.
