Teds car is now worth $9000 which is 60% of what he paid for it. what did he pay for this car?

amount pay for car is $15,000

Step-by-step explanation:

given data

car worth = $9000

paid = 60 %

to find out

$9000 is 60% of what number

solution

we consider amount pay = x

now we get here amount to pay for this car is express as

  .............1

put here value we get

9000 = ( x ) × 0.60

x =

x = $15,000

so  amount pay for car is $15,000

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

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.
