Answer:
<u>the order in which the ratio is drawn should be the same as listed.</u>
Explanation:
What this means is that since a ratio compares the sizes of two numbers (eg 4:2 or 4 ratios 2 or 
), it would be wrong to change the order of a ratio when drawn in a diagram.
For example, changing the order to (2:4 or 2 ratios 4), which then because 
not . Hence, it is important to remember that diagram of the ratio of two or more quantities should be the same as listed.
In the given sentence, 'The amount of gasoline remaining in the tank decreases with mileage driven' is the <em>mileage driven. </em>On the other hand, the dependent quantity in the given situation would be <em>the amount of gasoline. </em>This is because the amount of gasoline depends on the mileage driven.
They are simple linear equations with one unknown, lets tackle them, one step at the time solving for the unknown:
4x - 2(x - 5) = x + 13
4x - 2x + 10 = x + 13
2x + 10 = x + 13
2x - x = 13 - 10
x = 3
that is the solution.
3(6 - x) - 4 = 5x + 2(7x + 3)
18 - 3x - 4 = 5x + 14x + 6
14 - 3x = 19x + 6
14 - 6 = 19x + 3x
8 = 22x
x = 8/22 = 4/11
