Let's do the bracket part first,
and solve further as shown,
Answer:
x=53
x+2= 53+2= 55
Step-by-step explanation:
(x+2) + x + 72 = 180 (angles of triangle supplementary)
2x+ 74 = 180
2x = 180- 74
2x= 106
x= 106/2
x= 53
Amy bought 5 books for $0.50 and 7 for $.30, a total of 12
WORK
5 x .50 = 2.5
4.95 - 2.5 = 2.45
2.45 divided by .35 = 7
