Step-by-step explanation:
Supplementary angle adds up yo 180°
So angle 2 is supplementary to angle 3
 
        
                    
             
        
        
        
The solution is x=6 and y=5
        
             
        
        
        
Answer:
3rd choice
Step-by-step explanation:
9/5 = 18/10 = 1.8
All your numbers are between 1 and 2, and all have a fractional part that is a whole number of tenths. 1.3, 1.5, and 1.8 will be correctly shown by dots on the 3rd, 5th, and 8th marks.

Answer:
(3,0.5)
Step-by-step explanation:
The given system has equations:

Let us multiply the second equation by 4 and the first equation by 10.

We add both new equations to get:

Put x=3 into the first equation and solve for y.

The point of intersection is the solution to the system of equation which is (3,0.5)
