Answer:
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!

Answer:
1 feet wide
Step-by-step explanation:
We first need to find the area of the floor.
6*5=30
Then we divide the area by the number of kitchen tiles to get the area of each tile.
30/10=3
After this, we set up a L x W = A equation to solve for w.
3*w=3
3w=3
w=1
