The difference of three and the reciprocal of a number is equal to the quotient of 20 and the number. find the number.

Equation to find number: - 3 =

Number's value: n =

Step-by-step explanation:

Let n be the unknown number.

The reciprocal basically makes the number (n in this case) a fraction. So, that being said, the reciprocal of n would be .

The difference of three and the reciprocal of a number () would be - 3.

The quotient of 20 and the number (n) would be .

So, with this information we've gathered so far, we can come up with an equation to find what the number equals.

Equation: - 3 =

To find what the number equals we must solve the equation.

one that is bigger than 3 1/2

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:
