Answer:
The answer to your question is:
Step-by-step explanation:
12.- 
                 x² - 6x = 5
                 x² - 6x + (3)² = 5 + (3)²
                x² - 6x + 9 = 5 + 9
                (x - 3)² = 14
13.-           x² - 6x = 12
                x² - 6x + (3)² = 12 + (3)²
                x² - 6x + 9 = 12 + 9
               (x - 3)² = 21
               x - 3 = ±√21
               x1 = √21 + 3                     x2 = -√21 + 3
                x1 = 7.58                           x2 = -1.58
14.-           2x² - 24x = - 20             Divide by 2
                 x² - 12 x = -10
                x² - 12x + (6)² = - 10 + (6)²
                x² - 12x + 36 = - 10 + 36
               ( x - 6) ² = 26
                x - 6 = ±√26
x1 = √26 + 6                                 x2 = -√26 + 6
x1 = 11.1                                          x2 = 0.9
 
        
             
        
        
        
Answer:
to do this you need to Multiply 14 by 6 to satisfy the fact she has 6 times the amount of milk for 14 teaspoons of rennet
 
        
             
        
        
        
Set up a system of equations.
0.10d + 0.25q = 39.25
d + q = 250
Where 'd' represents the number of dimes, and 'q' represents the number of quarters.
d + q = 250
Subtract 'q' to both sides:
d = -q + 250
Plug in '-q + 250' for 'd' in the 1st equation:
0.10(-q + 250) + 0.25q = 39.25
Distribute 0.10:
-0.10q + 25 + 0.25q = 39.25
Combine like terms:
0.15q + 25 = 39.25
Subtract 25 to both sides:
0.15q = 14.25
Divide 0.15 to both sides:
q = 95
Now plug this into any of the two equations to find 'd':
d + q = 250
d + 95 = 250
Subtract 95 to both sides:
d = 155
So there are 95 quarters and 155 dimes.
