Is 0.4 bigger or 1/2 can u explain this to me

30 in the diagram line e and made parallel to each other and line p and q are transversal. use properties of special angles formed by parallel lines and their transversals to find the missing angle measures. m< 3=65 m< 15=120 m< 7= m< 4= m< 6= m< 1= m< 16= m< 18= m< 21= m< 10= m< 11= m< 12=

What is the solution to the system of equations? (–2, –8) (–1, –5) (0, –2) (2, 4)

If you answer right ill give brainliest, : )
