CAN SOMEONE PLEASE HELP ME WITH MY MATH CLASS PLEASEEE

-10/3≤x≤-5/3

Step-by-step explanation:

4≤-3x -1 ≤9

Add 1 to each side

4+1≤-3x -1+1 ≤9+1

5≤-3x  ≤10

Divide each side by -3, remembering to flip the inequality

5/-3 ≥-3x/-3 ≥10/-3

-5/3 ≥x≥-10/3

Rewriting

-10/3≤x≤-5/3

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:
