Answer: 30 minutes
Step-by-step explanation: First we can reduce the fraction 2/4 by dividing the numerator and the denominator by the greatest common factor of 2 and 4.
Since the factors of 2 are 1 and 2 and the factors of 4 are 1, 2, and 4, the greatest common factor of 2 and 4 is 2. So we divide the numerator and the denominator of 2/4 by 2 and we get the equivalent fraction 1/2.
Now we can change the question to say <em>1/2 of an hour is how many minutes?</em>
We know that 1 hour is equivalent to 60 minutes so half of 1 hour would be 30 minutes.
Therefore, 2/4 of an hour is 30 minutes.
 
        
             
        
        
        
Answer:
x = 15
Step-by-step explanation:
you have a straight line and a straight line measures 180.  You have a 90 degree symbol.
180 = 90 + 47 + 2x + 13
180 = 150 + 2x  Subtract 150 from both sides of the equation
30 = 2x  Divide both sides by 2
15 = x
