Jayden and Carson are selling T-Shirts and sweatshirts with the school logo. Jayden sells 9 T-Shirts and 3 sweatshirts for 288$. Carson sells 1 T-Shirt and 6 sweatshirts for 270$. Find the selling prices of each item

cost of T-shirts = $18

cost of sweatshirt = $42

Step-by-step explanation:

Let the cost of T-shirts be x

Let the cost of sweatshirt be y

The information given in the question can be used to form an equation that'll be:

9x + 3y = 288 i

1x + 6y = 270 ii

Multiply equation i by 1

Multiply equation ii by 9

9x + 3y = 288 iii

9x + 54y = 2430 iv

Subtract iii from iv

51y = 2142

y = 2142 / 51

y = 42

The cost of a sweatshirt is $42

Since Carson sells 1 T-Shirt and 6 sweatshirts for 270$. The cost of a t-shirt will be:

= 270 - 6(42)

= 270 - 252

= $18

$32,660

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.
