The sum of two numbers increased by 5

(x+y)+5

Step-by-step explanation:

To solve this, all you need is two variables to represent the 2 numbers. In this case, I used x and y. After that it says the sum of those 2 numbers increased by 5. All you need to know about that is that after x+y is done, you need to increase it by 5. So in this case,

(x+y)=5 satisfies the statement.

All the decimal numbers are beginning with 6 .

So just draw a circle .Write 6 in middle of the circle.

Then draw ten lines which starts from .60 and ends in .69.

you must draw lines in such a way that if you join all thes points it will also comlete  a circle.

A picture is shown below.

GENERAL METHOD: If you have to draw a decimal circle the positive integer being T then just draw a circle ,write T inside it  and start drawing equal line segments in all directions and at the end of the line segment mark ( T, T.1,T.2,T.3,T.4,T.5,T.6,T.7,T.8,T.9)

This will complete the whole circle.
