Answer:
b is greater than or equal to 5
Total value: $144
Explanation: each book cost $4.50
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

Answer:
1 3/4 - a<3/4
proof:
1 3/4 -a<3/4
=>1 3/4 - 1 3/4 -a<3/4- 1 3/4
=>-a<-1
=>a>1
