Apet store owner, byron, needs to determine how much food he needs to feed the animals. byron knows that he needs to order the same amount of bird food as hamster food. he needs four times as much dog food as bird food and needs half the amount of cat food as dog food. if byron orders 600 packages of animal food, how much dog food does he buy? let b represent the number of packages of bird food byron purchased for the pet store.

He needs to buy 120 packages of dod food.

Step-by-step explanation:

b - bird food

h - hamster food

d - dog food

c - cat food

b + h + d + c = 600

b = h (bird food is the same as hamster food)

b = 4 d (bird food is 4 times dod food)

c = d/2 (cat food is half dog food)

Total of packages ordered.

b + b + d + c = 600

4d + 4d + d + d/2 = 600

4 d + 4 d + d + d = 600. 2

10 d = 1.200

d= 120 the amount of dog food packages.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
