Five times the smallest of three consecutive odd integers is seven more than twice the largest. find the largest integer.

The largest integer is 9.

Odd numbers are numbers that cannot be divided into two equal halves without remainders. For example, 1 is an odd number.  Consecutive odd numbers are odd numbers that follow each other on the number line. For example, 1,3, 5.

Let the smallest integer by represented with x

The third largest integer would be x + 4

(5x) -  2(x + 4) = 7

5x - 2x + 8

5x - 2x - 8 = 7

3x = 15

x = 5

Largest number = 5 + 4 = 9

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:
