Danielle baked macaroni for her children for which she used up 19 th of a jug of milk. she also poured 20.5 ounces of milk into a bowl of cornflakes. if 25.5 ounces of milk remain in the jug, how much milk did the jug originally contain?

Milk in the jug was 48.56 ounces.

Step-by-step explanation:

Let the amount of milk in the jug = x ounces

Danielle used of the jug of milk so remaining milk in the jug =

=

She poured 20.5 ounces of milk into a bowl of cornflakes.

So the milk remaining in the jug =

If the remaining milk in the jug is 25.5 ounces ten we have to calculate the amount of milk the jug originally contained.

25.5 =

x = 48.56 ounces

Milk in the jug was 48.56 ounces.

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:

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
