The longest river in the world is the Nile River. It is 4,132 miles long. The longest river in the United States is the Missouri River. It is 2,540 miles long. Which is the best estimate of the difference in the lengths of the Nile and Missouri rivers?

Step-by-step explanation:

We want to solve the difference between the Nile River and the  Missouri River.

Given data

Length of the Nile River= 4,132 miles

Length of the  Missouri River=2,540 miles

A rough estimate or a guess from the  head for the difference will be around

1,600 mile

let us solve and see

difference= 4,132-2,540

difference=1592 miles

hence the difference is 1592 miles

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
