The libary has 441 storybooks and magazines altogther. There are 8 times as many storybooks as magazines. how many more storybooks than magazines are there in the library

There are 392 storybooks.

There are 49 magazines.

Step-by-step explanation:

s = number of storybooks

m = number of magazines

The library has 441 storybooks and magazines altogether.

s + m = 441

There are 8 times as many storybooks as magazines.

s = 8m

How many more storybooks than magazines are there in the library ?

Substitute s = 8m into the original equation to find m.

s + m = 441

8m + m = 441

9m = 441

m = 441/9

m = 49

Substitute m = 49 into the original equation to find s.

s + m = 441

s + 49 = 441

s = 441 - 49

s = 392

s - m = 392 - 49 = 343

392

Step-by-step explanation:

8 times of a story books

And there are 441 of both the magazine and story books

Let the magazine be x

And the story books be 8 times of x which means 8x

8x+x=441

9x=441

Divide both sides by 9

x=49

So there 49 magazines

To determine for storybooks

49×8=392

Therefore the number of storybooks is 392

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.

answer: 10 turtles

step-by-step explanation: as turtles have four legs so 4.10=40 therefore birds are 4 which sue counted
