Answer:
x = 6
Step-by-step explanation:
Vertical angles in a geometry are equal. Hence m<A = m<B
Given that
m<A = 3x - 9
m<B - x+3
Then 3x - 9 = x+3
3x - x = 3 + 9
2x = 12
Divide both sides by 2
2x/12 = 12/2
Hence the value of x is 6
x+y=18000
x= ammount of students
y= number of days or places going to
50 percent the cost of meals
you multiply -1.9 by -1
