Isabella works for a green house and is mixing food for the plants She will need 2 gallons of the food.

Solution:

Isabella works for a green house and is mixing food for the plants.

To make gallon she needs = of a gallon of the food

To calculate how much the food does she need if she wants to make 5 gallons.

If 1 gallon of mixture = gallon of food  

Then 1 x 5 = 5 gallons of mixture,  

x 5  

= gallons of food.  

10 divided by 5 is 2.  

Therefore, Isabella needs 2 gallons of food.

Result:

Therefore, the final answer is Isabella needs 2 gallons of food.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
