Question

Sue wrote a double fact it has a sum less than 10 and greater than 4 the addends are each less than 5 what fact might she have written

Answer 1

If the sum is less than 10 and greater than 4 that limits you to 5,6,7,8,9.
The addends are less than 5 so it could be 4+4, 4+3, 4+2, 4+1
This shows that Sue might have written 5,6,7, or 8.

Answer 2

`4 < x+y<10`

`x < 5, y < 5`

Explanation:

We are given the following information in the question:

Let x and y be the two addends whose sum is being evaluated.

It is given that the sum is greater than 4 and smaller than 10. This can be written with the help of inequality:

`4 < x+y<10`

Also, each addend is less than 5. This can the written in the form of inequality:

`x < 5, y < 5`

If we solve these linear inequalities in two variable, we may be able to get the values of x and y.

The common area of the following inequalities gives us the solution to the problem. There could be various values of x and y to give the solution of these inequities.
