Carlos wants to purchase a new tennis racket and decides to purchase some tennis balls as well. His racket cost 55 dollars and each ball costs 2 dollars. If he has 80 dollars, how many tennis balls can he buy? A) Write the equation that represents this situation.
B) How many tennis balls can he buy?

80-55=25

then

25/2=12.5

he can bye 12.5 balls

Step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
