Answer:
C. = 
Step-by-step explanation:
Note the conversion for Yard to Feet. 
1 yard = 3 feet.
In this case, it is given to you that there are 4 yards. Multiply 4 with 3 to get the amount of feet: 
4 yd x 3 ft per yd = 12 feet per 4 yd. 
12 ft. = 12 ft., ∴ 4 yd. = 12 ft.
 
        
             
        
        
        
Answer:
$92.33
Step-by-step explanation:
You take 143.75 and multiply by .3 to find the amount you will discount from 145.75, to get 102.025. Then multiply that by .095 to get 9.692375. Subtract that from 102.025 to get 92.33.

Don't let fractions fool you.

 of a tank in 

 an hour is equal to:
1/12 of a tank in 20 minutes.
Thus we know in an hour, an oil company can fill 3/12 of a tank (60 minutes in an hour).
3 x 4 = 12, and 12/12 = 1(a whole tank), so we multiply 1 (hour) by 4.
Our answer is that it takes 4 hours to fill a tank.
 
        
        
        
In order it  goes like this 
- 4^ x - 1 = 3^ (-x) - 2
- 3 x + 6 = 2^ x + 1
3^ x - 3 = 2 x - 2
so the question is the answer
