Acar with a tank that holds 11.6 gallons of gasoline is using 1.45 gallons per hour. is the tank more than half full of gasoline after 3.5 hours? explain your answer.

NO because 5.075g (gasoline available after 3.5 hours) < 5.8g( half full tank)

Step-by-step explanation:

Hi, to solve this problem we have to calculate how many gallons has a half-full tank. If the tank holds 11.6 gallons we have to divide it by 2.

So, to know if the tank is more than half full of gasoline after 3.5 hours we have to multiply the gallons used in an hour (1.45) by the amount of time (3.5) and compare.

In conclusion, after 3.5 hours the the tank is not more than half full of gasoline, because 5.075 < 5.8.

Feel free to ask for more if it´s necessary or if you did not understand something.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
