Answer:
three thousand and ninty-four
Step-by-step explanation:
I think thats the right answer :)
It's closed under addition. You can take any two natural numbers you want, add them up and you'll get some other natural number (eg: 3 and 5 ---> 3+5 = 8)
it's not closed under subtraction. Sure 5-3 = 2 is a natural number but 3-5 = -2 is not a natural number
so that leads us to the answer being choice B
6x = 33 x= 33/6. x= 5 3/6 = 5 1/3
2/3x=8/15= x= 8/15÷2/3 x= 8/15 x 3/2 = 24/30 = 4/5
