What is the monetary amount of 31 quarters, 13 dimes, 5 nickels and 3 pennies?

$9.33

Step-by-step explanation:

quarter = 25 cents

dime = 10 cents

nickel = 5 cents

penny = 1 cent

31 (0.25) = 7.75

13 (0.10) = `1.30

5 (0.05) = 0.25

3(0.01) = 0.03

7.75 + 1.30 + 0.25 + 0.03 = 9.33

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.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
