1/2 +b=1 3/4

what does b represent and how to solve it?

b= 5/4 or 1 1/4

Step-by-step explanation:

First I will make 1 3/4 into an improper fraction

1/2 + b = 7/4

Then I will make the fractions have common denominators

2/4 + b = 7/4

I subtract 2/4 from 7/4

b= 5/4

b represents the unknown number, the number that we are finding by solving this equation

b = 1 1/4

or, in decimal form

1.25 = b

Step-by-step explanation:

1/2 + b = 1 3/4

b = 1 3/4 - 1/2     >      1/2 = 2/4

b = 1 3/4 - 2/4

b = 1 1/4

or, in decimal form

1.25 = b

b represents the unknown number, the number that we are finding by solving this equation

this doesn't make sense lol

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.
