3/4n=-1 3/4n-18

Step by step please

Solving the expression we get

Step-by-step explanation:

We need to solve the expression:

Solving:

First we convert mixed fraction into improper fraction

Now adding 7/4 n on both sides

Now, taking LCM on left side

LCM of 4 and 4 is 4

Now, multiply both sides by 4/10

So, solving the expression we get

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:

it is 32.5
