1 billion is 1,000 million 1,000,000,000
so
27,003,095,000
-19/15
you multiply boh sides by the other denomonater
-10 and -9
15 15
10 15 20 since i am pretty sure the rest are a triple(definitely 3 4 5 and 7 24 25 is a triple0
5x - 100 + x - 20 = 180 (sum of supplementary angles is equal 180)
6x - 120 = 180
6x = 300
x = 50
x - 20 = 50 - 20 = 30
so
3y = 30 (vertical angles are equal)
y = 10
