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
You would divide both sides by 0.75, to get a=-12.
I think this is a one- step equation, but that is the only way I think you can solve it.

Answer: A
Explanation do Pythagorean theorem and find the third side. Then do adjacent/hypotenuse.
#11 3/8+5/24=14/24= 7/12
#12 9/20-1/4=9/20-5/20=4/20=
