Answer:
She will need 2 gallons of the food.
Step-by-step explanation:
If 1 gallon of mixture = 2/5 gallon of food, then 1 x 5 = 5 gallons of mixture, and 2/5 x 5 = 10/5 gallons of food. 10 divided by 5 is 2. Therefore, Isabella needs 2 gallons of food.
Answer:

Answer: flight to NYC
distance: 740 rate: 495+x time: 740/495+x
flight home:
distance: 740 rate: 495-x time: 740/495-x
Step-by-step explanation: the plane is flying with the wind when flying to NYC so the planes speed, or rate, can be modeled as 495+x
on the flight back home plane is flying against the wind so the planes speed, or rate, can be modeled as 495-x
multiply across the table to find the time each journey will take by using the equation time=distance/rate. Hope this helped :)
