426 to nearest ten is 430 because the rule is 1-4 is rounded to the 0 and 5-9 is rounded to the ten place. You just basically look at the place value and round it.

We look at the tens place

20 is in the tens place

now look at the Ones place

6 is in the Ones place

If it is 5 or greater we round it to the next ten, if it is 4 or less we keep it the same

6 is greater than 5

The number will be rounded to 430

You would change the denominator and get the lowest common denominator. Thos would be 30. You would do 11/6 x 5/5 = 55/30. Then do 3/5 x 6/6 = 18/30. Then add 55/30 + 18/30 = 73/30 and simplify.

three vertices of a rectangle are located at (5,3), (7,1), and (1,-1). what are the coordinates of the fourth vertex?

SVETLANKA909090 [29]

I first plotted the three points and from from their position it was clear which pairs to join to start a rectangle.

At this point you need to check to make sure the angle at B is a right angle. Find the slope of the line segments AB and BC and check that the product of the slopes is -1.

From the diagram you can now see where the fourth point D has to be. If AB and CD are parallel then D must be 3 units to the left of C and 2 units above C. Find the coordinates of D and then check by finding the slopes of CD and DA and showing that the angle at D is a right angle.

I hope this helps
