Jess had three more nickels than dimes for a total of $1.50 how many of each coin did he

n = d + 3

5n + 10d = 150 cents

Substitute to solve for "d":

5(d+3)+10d = 150

15d + 15 = 150

15d = 135

d = 9 dimes

n = d+3 = 9+3 = 12 nickels

So 12 nickels!!

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.
