Solve the inequality -2x+20<2x+4

x<4

Step-by-step explanation:

-2x+20<2x+4

−2x+20−2x<2x+4−2x

−4x+20<4

−4x+20−20<4−20

−4x<−16

−4x/-4<-16/-4

x<4 its a open circle

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:
