Answer:
#5 x=8, #6 x=5
Step-by-step explanation:
Theyre vertical so for number 5 you would have the equation
5x+15=55
     -15   -15 from both sides
5x=40
divide by 5 from both sides and you get
x=8 
Same thing vertical so you would have   
16x+7=87
     -7    -7 from both sides
16x=80
divide by 16 from both sides
x=5
 
        
             
        
        
        
Answer:
Rational.
Step-by-step explanation:
Since it can be put into a fraction, negative or positive it is clearly rational. Irrational numbers are numbers we can never know the true value because they repeat forever (pi for example)
 
        
                    
             
        
        
        
Answer:
students 150
adult 550
Step-by-step explanation:
x + y = 700
5x + 2y = 3050
x = 700 - y
5(700 - y) + 2y = 3050
3500 - 5y + 2y = 3050
-3y + 3500 = 3050
-3y = 3050 - 3500
-3y = -450
y = -450 / -3
y = 150
x = 700 - y
x = 700 - 150
x = 550
