EF = 50 in.
In similar figures, corresponding sides are proportional. We use the similarity statement ABCD~EFGH to write a proportion:

Cross multiply the proportion:
45*x = 75*30
45x = 2250
Divide both sides by 45:
45x/45 = 2250/45
x = 50
15n > 12n + 18
3n > 18
n > 6
3/5 + 7/10 / 7/12 - 3/10
13/10 / (35/60 - 18/60=)17/60
10/13 x 60/17 = 78/17 = 4 10/17
Answer:
11/12
Step-by-step explanation:
1 2/12 = 14/12
14/12 - 2/12 - 1/12
since they all have 12, it doesn't matter until the end
14 - 2 = 12 - 1 = 11
put the /12 behind the 11 and you have an answer
