Answer:
7 : 1
Step-by-step explanation:
Paul's car goes 40 kilometers on 7 tanks.
Distance : Tanks
49 : 7
Fuel efficiency means the distance traveled by the car in one tank.
Therefore, we will reduce the ratio by dividing both sides by 7.
Distance : Tanks
: 
7 : 1
Therefore, car's fuel efficiency is 7 kilometers in one tank or the ratio between Distance traveled and fuel tanks is 7 : 1.
Answer:

Step-by-step explanation:

Comparing to

Where A,B,C are constants
You should see that we need to substitute the
with u.
Set on of the numbers as x. The consecutive integer to it would be x+1 (or x-1, which ever one you like. I'm going to use x+1 though).
The sum would be
x + (x+1)
Set it equal to 59.
x+x+1=59
2x+1=59
2x=58
x=49
One integer is 49. The other integer, x+1, is 50.
Hope this helps!
