Answer:
- 126 children
- 63 adults
- 60 students
Step-by-step explanation:
Let a represent the number of adults that attended. Then 2a is the number of children, and (249 -a -2a) is the number of students. The total revenue is ...
5(2a) +7(249 -3a) +12a = 1806
a +1743 = 1806 . . . . simplify; next, subtract 1743
a = 63 . . . . . . . . adults
2a = 126 . . . . . . children
249 -3a = 60 . . students
126 children, 63 adults, and 60 students attended.
Ex: f: R ---> R
f(x)=2x+1
Definition: For every value of x , exists only one value of f(x)
f(1)=2*1+1, f(1)=2*1+1=3
f(2)=2*2+1=4+1=5
......
f(100)=2*100+1=200+1=201

Step-by-step explanation:
32 - 7x = 2x - 3(4x - 5) ← distribute parenthesis
32 - 7x = 2x - 12x + 15
32 - 7x = - 10x + 15 ( add 7x to both sides )
Anna made her error here in that she subtracted 7x from both sides
32 = - 3x + 15 ( subtract 15 from both sides )
17 = - 3x ( divide both sides by - 3 )
-
= x ← is the solution
