20x^2+50 = -40x^2+110x [ Taking x as the unknown positive integer ]
Answer:
Rational
Step-by-step explanation:
1.256 is not a whole #, and it's also not an integer. An integer is basically whole #s and their opposites. The # is not irrational. 1.256 is a terminating decimal, and can be turned into a fraction. 1.256 = 1 32/125.
Supplementary angle must add up to 180 so the supplement will be 108 degrees. 180-72=108.
Ratio means only one thing but I think what you meant was 3 examples of a ratio. In that case three examples would be:
2:3,
2 to 3,
2/3
