Mrs. Carlyle bought a bag of peanuts for her children. When Phillip, Joy, Brent, and Preston came home from school, they each took some peanuts from the bag. Phillip took 1/3 of the peanuts from the bag.
Joy took 1/4 of the remaining peanuts.
Brent took 1/2 of the remaining peanuts.
Preston took 10 peanuts.

71 peanuts were remaining in the bag.
How many peanuts were originally in the bag?

2. How many peanuts did each child take? ​

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

the answer is d
