Lisa bought 9 gallons of ice cream

Step-by-step explanation:

lets take "x" as the gallons of lemonade

if Lisa made purchases worth $34 that is what our equation will e equal to

ice cream:7.5 per gallon

milk: 2.5 per gallon

lemonade: 3 per gallon

since Lisa purchases 4 gallons of milk and 2 gallons of ice cream we will multiply that by the unit money for each food respectively:

7.5(2)+2.5(4)+X=34

SIMPLIFY:

15+10+x=34

15+10=25

25+x=34

25-25+x=34-25

x=9

Lisa bought 9 gallons of ice cream

hope this helps!

where is the passage?

can't without the passage.

post the full question.

        i'm fairly sure that the correct answers are 2 and 3.

        i used both my knowledge of world history and the process of elimination to obtain these answers. option 1 cannot be a possible selection because the mandate of heaven belongs to ancient chinese philosophical belief. option 4 sounds like it would benefit the region than detriment it. however, both 2 and 3 explain a potential reason for what could have contributed to the fall of the roman empire.

      hope this ! if i were you, i'd get a second opinion, because i haven't taken this course for a year. best of luck!
