Answer:
Step-by-step explanation:
Let
g ----> number of gallons of gasoline
c ---> the total cost in dollars
we have
<em>First gas station</em>
This is a proportional relationship between the variables c and g
The constant of proportionality k or unit rate (slope) is equal to
<em>Second gas station</em>
we have the ordered pairs
(2.5,8.30) and (5,16.60)
This is a proportional relationship between the variables c and g
The constant of proportionality k is equal to
the linear equation is
To find out how much per gallon would Billy save, subtract the unit rate of the Gas station 1 from the unit rate of the Gas station 2
so
To find a common denominator you have to find a number that both can be divided by in this case, 15. So both can be set to 15. However the numerators must also be changed. Since 15 divided by 5 is 3, the numerator 2 should be multiplied by 3 to get 6. Then since 15 can be divided by 3 to 5, you multiply 5 to the numerator 1 to get 5.
Then do
6/15 - 5/15 to get 1/15
Answer:
Step by step explanation:
600 meters
Cause if you find multiples of 30 (for meters of course) 6 goes into it 5 times, which a fraction for 20%=1/5. So if you multiply 6 by 5 you get 30. After you can just add 2 zeros to the equation and its the same thing, But Just in bigger numbers.
Feel free to correct anything wrong. I wouldn't mind changing the answer if its wrong. :)
