Answer:
-56
Step-by-step explanation:
2(i).
(3y-20)+(4x-5)+(x+y-10)+(2x+5)=360 (Angles sum of it trapezium)
3y-20+4x-5+x+y-10+2x+5=360
7x+4y=390
(Shown)
2(ii).
(3y-20)+(2x+5)=180 (Interior Angles, Parallel Lines)
2x+3y=195

Least to greatest: 7/12, 0.75, 5/6
Explanation:
Leave 7/12.
5/6 is equivalent to 10/12 if you multiply the numerator and denominator by 2.
0.75 is equal to 75/100, which is equal to 3/4 if you divide numerator and denominator by 25. 3/4 is equal to 9/12 if you multiply by 3.
You can look at the three numbers as 7/12, 10/12, and 9/12.
