A Car can Travel 82 miles on 2 gallons of gasoline. How Far can it travel on 9 gallons?​

369 miles

Step-by-step explanation:

82 miles =2 gallons

41 miles = 1 gallon

369 miles = 9 gallons

369 miles

Step-by-step explanation:

Distance travelled in 1 gallon gasoline = 82 miles

So, distance travelled in 1 gallon gasoline

= distance travelled in 2 gallon gasoline/2

= 82 miles/2

= 41 miles

So, distance travelled in 9 gallons gasoline

= distance travelled in 1 gallon gasoline × 9

= 41 miles × 9

= 369 miles

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
