<h2>Answer:</h2>

<u>Venn diagram </u><u>is one kind of diagram we might draw as intersections of the circles.</u>

<h2>Step-by-step explanation:</h2>

A Venn diagram is a diagram that shows all possible logical relations between a finite collection of different sets. These diagrams depict elements as points in the plane, and sets as regions inside closed curves. They are usually used  to graphically organize things and show how the items are similar and different.

You can use a bar graph or histogram to compare amounts of items  You can also draw arrays to help with multiplication problems.  
In algebra, you can graph equations to see points of sets.

Hope this helps!

Lily bought 6 skirts and 5 coats for a total of $452.62. If Lily's
PSYCHO15rus [73]

Let x = cost of one skirt

Let y = cost of one coat.

We need to construct a system of equations to help us solve this problem.

Lily: $452.62 = 6x + 5y

Sis: $289.36 = 3x + 5y.

Let's solve this by elimination. Multiply the second equation by -1

Lily: $452.62 = 6x + 5y

Sis: -$289.36 = -3x + -5y. Add the equations together.

$163.26 = 3x. Divide each side by 3.

$54.42 = x. Plug this into one of our original equations.

$452.62 = 6(54.42) + 5y. Multiply 6 by 54.42

$452.62 = 326.52 + 5y. Subtract 326.52 from each side.

$126.1 = 5y. Divide each side by 5

$25.22 = y.

One coat costs $25.22

Imagine reflecting triangle ABC across line MN. Then answer the questions about the reflected figure.
EastWind [94]

Answer:

triangle

Step-by-step explanation:

Reflection of an figure across any line is the mirror image of the figure.

That means reflection of a figure is a rigid transformation, in which size or shape of the image doesn't change.

Therefore, when we reflect triangle ABC across the line MN shape of the reflected angle will remain same as a triangle.
