Answer: $9-(0+1+2)$

Step-by-step explanation:

We have given the numbers = 2,0,1,9

We can use addition and subtraction operation to the given numbers such that the answer will be equals to 6.

We can add 2 ,0 and 1 and then subtract from 9 , we will get 6.

So the required expression can be

$9-(0+1+2)\\=9-(3)\\=9-3\\=6$

hence, the required expression can be $9-(0+1+2)$

5x + 2 1/4 = 19 1/8
5x + 9/4 = 153/8
5x = 153/8 - 9/4
5x = 153/8 - 18/8
5x = 135/8
x = 135/8 * 1/5
x = 135/40 = 3 3/8 inches <==
