The answer is 125. If you were to pair 250 people in 2, that would be 250 divided by 2. And 250 divided by 2 is 125.
The digit 6 is in the Hundred Thousand Place.
Not sure what you’re trying to find but here’s the simplified version:
-4<=2t+5<11
-9<=2t<6
-9/2<=t<3
Everywhere you see z, replace the letter with 18.
z/[(3- 2z)] + 4(z - 8)
18/[(3 - 2(18))] + 4(18 - 8)
You finish.
