3/4 - 1/5 divide by 2/5 can you give the answer and step by step instructions on how you got it

Step-by-step explanation:

Find the attachment below for a step by step explanation.

Step-by-step explanation:

We are given the following fractions to divide:

Taking LCM of the fractions in the numerator to simplify it into a single fraction:

Taking reciprocal of the fraction in the denominator to change it to multiplication:

×

Changing this improper fraction into a mixed number:

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: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
