Best ResponseYou've already chosen the best response.0car A averages 16 miles a gallon car B average 35 miles a gallon at this rate how much more gallons will car A and B need to make a 1120 mile trip

phi

Best ResponseYou've already chosen the best response.1if you multiply 1120 miles by the ratio of gallons/mile , you will get gallons in other words, car A will use \( 1120\ miles \cdot \frac{1\ gallon}{16 miles} \) and car B will use \( 1120\ miles \cdot \frac{1\ gallon}{35 \ miles} \) and the difference is \[ 1120 \cdot \frac{1}{16 } 1120 \cdot \frac{1}{35 } \]

Best ResponseYou've already chosen the best response.1if you don't have a calculator you can do the division in steps (it helps to know some "rules" see https://en.wikipedia.org/wiki/Divisibility_rule) for example, 16 is 4*4 divide 4 into 1120 to get 280 then divide that by 4 to get 70 we have 70  1120/(5*7)

Best ResponseYou've already chosen the best response.1first add up the x's. how many x's do you have?

phi

Best ResponseYou've already chosen the best response.1for example x+x is 2x when you add up the x's you get 5x (not just 5) now add up the numbers. what do you get ?

phi

Best ResponseYou've already chosen the best response.1yes, but you can simplify the numbers and get just 1 total for the numbers

Best ResponseYou've already chosen the best response.1in other words do 32 1+1

phi

Best ResponseYou've already chosen the best response.1yes. all of that means the sum of the "x stuff" is 5x5 and they say they add up to 390 we can say 5x5= 390 add 5 to both sides 5x5+5 = 390+5 and simplify. what do you get ?

phi

Best ResponseYou've already chosen the best response.1on the left side you have 5+5 which adds to 0 so 5x+0 on the left but adding 0 does nothing, so we can just say 5x= 390+5 what do you get on the right side?

phi

Best ResponseYou've already chosen the best response.15x= 395 divide both sides by 5 x= 395/5 = 79
