Answer:
   -35.626 < temperature < 733.928 . . . . degrees F
   (-35.626, 733.928)
Step-by-step explanation:
It is convenient to let a calculator evaluate the expression for converting °C to °F.
   -35.626 < temperature < 733.928 . . . . degrees F
   (-35.626, 733.928) . . . . . . . . . . . . . . . . . in interval notation
_____
The given relation is C = 5/9(F -32). The inverse relation is F = 9/5C +32. That is the relation we need to use to answer this question.
 
        
             
        
        
        
Answer: A and B
Explanation: A sum is an answer to an addition problem and a difference is the answer to a subtraction problem. N is the sum to the addition problem and -n is the answer to a subtraction problem.
 
        
                    
             
        
        
        
Answer:
33.18
Step-by-step explanation:
Use law of sines.
x / sin(65°) = 21 / sin(35°)
x = 21 sin(65°) / sin(35°)
x ≈ 33.18

Answer:
11
Step-by-step explanation:
Those are alternate exterior angles.  IF the lines A and B are parallel, then those angles are equal.  Set them equal to each other and solve for x:
5x + 9 = 6x - 2
Combine like terms:
11 = x
