Step-by-step explanation:

You can first start with 7 10s.

10,10,10,10,10,10,10

Now, to make the range 10 as well, the greatest and least value must differ by 10. In other words, you want a set of two numbers that have a mean of 10, but a range of 10. We see that 5,15 works. So we combine that set with another set of 5 10s.

5,10,10,10,10,10,15

If we have another set with a range of 10, for example 4,14, we need another value to balance the drop in the mean. We can add a 12 to make

4,10,10,10,10,12,14
