Answer:
Step-by-step explanation:
Red =x Blue = y
1) 4x + 6y = 180
2) x + y = 40
solve for x in eq. 2 and plug into eq. 1
2a) x=40-y
1a) 4(40-y) + 6y = 180
160-4y +6y = 180
2y=20
y=10
plug into eq. 2
x + 10 =40
x=30
30 red packages
;) maybe a late Christmas gift.. :D
1. -6x + 14 < -28
6x<42
x<7
2. 3x + 28 < 25
3x < -3
x<-1
Hope This Helps!!!
