You will drive 200 miles and need to calculate your gas expense (25km per gallon and gas costs $6.00/gallon).
makvit [3.9K]
First you do 200 miles divided by 25 km. It is 8. This means you need 8 gallons for the whole trip. 8 times 6dollars is 48 dollars. You will need to pay 48 dollars in gas prices.

This is a question on proportions in geometry. Image has been shared.
Digiron [165]
A+b       5
------- = ---
2a-b      4

  b           5
-------- = ----  => 9b = 5a+45 => b = (5a+45)/9
 a+9       9


a+b       5
------- = --- => 4a+4b = 10a-5b
2a-b      4

9b = 6a

9(5a+45) =6a   divide both sides by 3

3(5a+45) = 2a

15a +135 = 2a

13a = -135

a = -135/13 = -10,38

a= -10,38

9b=6a

3b=2a

3b = 2(-10,38)

3b = -20,76

b = -20,76/3

b = -6,92

hope this helped
