After the division, we get 8.99031476998. This rounds to <u>9</u> as a whole number, which is the answer.
When rounding to a whole number, the digits following the decimal decide what number it rounds to. If it is 0-4 it rounds to whatever the whole number currently is E.G.
8.1 would round to 8
But if its 5-9 it rounds to one above, like in our current case.
8.5 rounds to 9.
42.414 rounds to 42.
42.94149124 rounds to 43.
y=2x so replacr the -y with -2x so 2x+6 is 8x. :)
The answer would be D because it's the only one that makes sense
