Answer: 1/6
Step-by-step explanation: Let the no of females be x
The no of males be 5x
The total no of males and females in the math course be 5x+x= 6x
The fraction of females is x/6x = 1/6
 
        
             
        
        
        
Answer:
Second one is -30, 20, -50

Step-by-step explanation:
 
        
             
        
        
        
300 miles in 1h 40m
300 miles in 100m
300 / 100 = 3
3 miles per minute
3 x 60 = 180
180 miles per hour

Answer:
The given set of equation are:    x+ (-45) ≤  35  ,  x - (-45) ≥  35 
For the given equality to be true, x  ≤ 35
Step-by-step explanation:
Here, given the first number = x
Second number  = -45
Now, Sum of x  and - 45 is at most 35.
⇒  x+ (-45) ≤  35
Also,  The difference of x and -45 is at least 35.
⇒  x - (-45) ≥  35 
Now, simplifying the given set of equations:
x  - 45  ≤  35   ⇒    -x - (-45) >   - 35   ( as 3  <  4  ⇒ -3  > -4)
or, -x  + 45  >  - 35
 and second equation is x  + 45 ≥  35 
Now, solving both the equations by not taking sign of inequality in to the consideration, we get
x - 45  = 35
x + 45 = 35  
Adding both equations,we get:   ⇒ 2x = 70
                                                           or x = 35
Hence for the given equality to be true, x  ≤ 35
