Answer:
9
Step-by-step explanation:
We want something that equals 19 right? Anything can work here such as
10+9=19 <---we have our outcome as 19
If you want something more complex
<span>1(10)+10-1=?
</span>When you solve that it equals 19! :)
The value of 7 in 7,283 is 10 times the value of 7 in 2,783
