Answer:
1. 8.85 quarts 
2. 44.25%
Step-by-step explanation:
In 15 quarts of a solution with percentage of antifreeze = 35%
Amount of antifreeze = 35% × 15
                                     = 0.35 × 15
                                     = 5.25 quarts
that solution is mixed with 5 quarts of a solution with percentage of antifreeze = 72%
Amount of antifreeze = 72% × 5
                                     = 0.72 × 5
                                     = 3.6 quarts
Total amount of mixture = 15 quarts + 5 quarts = 20 quarts
1. Now we will calculate the total amount of antifreeze in the resulting mixture.
= 5.25 + 3.6 = 8.85 quarts
2. The percentage of the resulting mixture is antifreeze
= 
= 44.25%
1. total amount of antifreeze is 8.85 quarts 
2. the percentage of antifreeze is 44.25%
 
        
             
        
        
        
Answer:
x = 5
Step-by-step explanation:
Add the degrees of m<VUJ and m<JUT and make them equal to 175 since both angles exist with m<VUT. 
17x - 3 + 17x + 8 = 175 
34x - 3 + 8 = 175 
34x + 5 = 175 
34x = 170 
x = 5 
 
        
             
        
        
        
Slope = (y2 - y1)/(x2 - x1)
Slope = (212 - 32)/(100 - 0)
Slope = 180 / 100
Slope = 18/10
Slope = 9/5
Answer
D. slope = 9/5
 
        
             
        
        
        
Answer:
9/4x to the power of one plus 12y to the power of one
Step-by-step explanation:
You can add the top numbers for 9, but cant add the bottoms since they are different variables.
 
        
                    
             
        
        
        
Answer: B
Step-by-step explanation:
-9 - 6 - (-8) = -9 - 6 + 8 = -7
