Answer:
-3x + 3y - 6
Step-by-step explanation:
2x + 3y - 4 - (5x + 2)
open brackets by using - sign to multiply
2x + 3y - 4 - 5x - 2
collect like terms
2x - 5x + 3y - 4 - 2
-3x + 3y - 6
So, first off it would help if you could define the terms irrational number and integer. Well, an irrational number is basically any real number that can't be expressed as a ratio of integers. They also cannot be represented by terminating or continuing decimals. And an integer is pretty much any number that cannot be written as a fraction or decimal, such as -2, 13, 257. It is not 2 and 1/2, or 4.75. Those would not be integers. Do you think you can figure out the difference?
The easiest way to compare fraction is to make them all have the same denominator and then you can just compare the numerators...
-1/6, (5/3)(2/2), -5/6
-1/6, 10/6, -5/6 so from least to greatest
-5/6, -1/6, 10/6
-5/6, -1/6, 5/3
Two significant figures.
The trailing zero is not significant
