The sum of the percentages of milk and dark chocolate needs to equal 100%.
Since dark chocolate is 25%, then milk chocolate must be 75%
Now we can set up a proportion:
75% = 3 lbs
25% = X lbs
Dark chocolate = (3 x 25%) / (75% x X) = 1 lb

Answer:
x=2, y=1. (2, 1).
Step-by-step explanation:
x=2y
2x+5y=9
-------------
2(2y)+5y=9
4y+5y=9
9y=9
y=9/9
y=1
x=2(1)=2
Answer:
Answer:
m∠2= 86
Step-by-step explanation:
since they are vertical angles, that means they are both equal to eachother.
so lets set them equal!
17x+1=20x-14
17x+15=20x
15=3x
x=5
now input x into m∠2
m∠2 = 20(5) – 14 = 86
