One car 40 miles /gallon
other car 30 miles/gallon
..
Total miles = 165
gas used = 45 gallons
...
let first car drive x miles
second car drive y miles
..
x/40 + y/30 = 45
(30x+40y)/30*40 = 45
30x+40y = 45*40*30
30x+40y=54,000
Answer:
y=1/3x + 2
Step-by-step explanation:
the y intercept is 2, and the second point goes up 1 over 3
rise over run
Answer:
46
Step-by-step explanation:
The complete square starting with 
would be 
, since the square would be 
. To make this square perfect, then, you would need to add 46 to make 49 with the 3. Hope this helps!
Okay so 300 meters per minute and he ran 8 minutes..
300x8=2400
He still had 600 left to go...
2400+600=3,000
He had to run three times longer than Eric...
3000/3=1000
Does that make sense?
