Answer:
So since the scale is 12 inches:5 feet, we have to divide 412 inches by 12 inches because 412 inches is the total length drawn on the scale drawing. 
412/12 = 34.3 
Then since each 12 inches equals 5 feet and we have 34.3 12x inches. We are just going to multiply 34.3 by 5.
34.3*5 = 171 and 2/3 feet is your actual length of the bus
 
        
             
        
        
        
What you want to first is substitute the numbers in for the variables in the equation 
Since b= -5 , we will plug it in for -b
-5 + c = -13x 
Now plug in -8 for c 
-5 + (-8) = -13x
Add the numbers on the left side, which gives you -13. 
-13 = -13x 
Lastly, divide both sides by -13x, which will give you 1.
So x = 1
        
             
        
        
        
Answer:
300 gallons an hour
Step-by-step explanation:
If it pumps 75 gallons in 1/4 of an hour (15 minutes), then if you times that by four to make it a full hour (60 minutes). 75 times 4 is 300.
 
        
             
        
        
        
7(6) x 7(5) = 7(6+5) = 7(11) is the simplified answer.
Thank you!
