Answer:
Step-by-step explanation:
G is the centeroid of the triangle. G splits AE in the ratio 2 : 1
AG : GE = 2 : 1
AG = 2x and GE = x
2x = 20
x = 20/2
x = 10
GE = 10 ; AG = 20
AE = 20+10 = 30
CG : GD = 2:1
CG = 2x and GD = x
2x = 10
x = 10/2
x = 5
GD = 5
BF = 30
BG : GF = 2 : 1
BG = 2x ; GF = x
BF = 30
BG + GF = 30
2x + x = 30
3x = 30
x = 30/3
x = 10
GF = 10
Answer: The weight of the box is 0.2 pounds and the weight of the chocolates before any chocolates were taken out is 2 pounds
Step-by-step explanation:
Let x represent the weight of the box only.
The weight of the box of chocolates is 2.2 pounds. It means that the weight of the chocolate only is
(2.2 - x) pounds
After taking out 75% of the chocolates, the remaining chocolates and the box weigh 0.7 pounds. It means that
2.2 - 0.75(2.2 - x) = 0.7
2.2 - 1.65 + 0.75x = 0.7
0.75x = 0.7 + 1.65 - 2.2
0.75x = 0.15
x = 0.15/0.75
x = 0.2 pounds
The weight of the chocolates before any chocolates were taken out is
2.2 - x = 2.2 - 0.2 = 2 pounds
