DiKsa [7]
First, multiply $3 by 4 to get $12 spent on cookies.  Then, you multiply $12 by 2 to know that the pies cost $24.  You then divide the $24 by 3 to get $6 per pie.  Meaning, each pie had cost $6.  You add the $12 and $24 together to get $36.  Finally, you subtract $36 from $40 to know that she only has $4 left.

using the midpoint formula find the coordinates of the midpoint 9f each sigment with end points (4,2),(-5,-1)​
exis [7]

Answer:

The midpoint of the segment is (-0.5,0.5).

Step-by-step explanation:

Midpoint of a segment:

The midpoint of a segment is given by the mean of its coordinates.

Segment with end points (4,2),(-5,-1)​

x-coordinates: 4 and -5

y-coordinates: 2 and -1

x-coordinate of the midpoint:

x = \frac{4-5}{2} = -\frac{1}{2} = -0.5

y-coordinate of the midpoint:

y = \frac{2-1}{2} = \frac{1}{2} = 0.5

The midpoint of the segment is (-0.5,0.5).
