Kaylis [27]
Amount of fuel in the tank before the story begins . . . . . zero.

Total amount poured in . . . . . 3/4 gallon.

Total amount burned:
                   on Friday . . . . . 1/4 gallon
                   on Sunday . . . . 1/4 gallon
                        Total used . . 1/2 gallon .

Amount remaining in the tank on Monday:

               (3/4 gallon in) - (1/2 gallon burned)  =  1/4 gallon left.
                                                                        ==>  NOT empty

The tank would have been empty on Monday IF Becky
had poured in only 1/2 gallon, instead of 3/4 of a gallon
before the first flakes began to fly.

Whats the step by step answer to this equation i got -25 but its supposed to be positive not negative
andreev551 [17]

Answer:

25

Step-by-step explanation:

  • - 6/5x = -30               ⇒ multiply both sides by -1
  • 6/5x = 30                  ⇒ multiply both sides by 5
  • 6x = 5*30
  • x = 150/6                   ⇒ divide both sides by 6
  • x = 25                        ⇒ answer
