Let P be the cost of pucks, S the cost of sticks.
1.5p+3s=23
2.5p+s=20
subtract eqn 2 from 1,we get
5p+3s-5p-s=23-20
2s=3
s=3/2=1.50
Then from eqn 2,
5p+3/2=20
5p=40/2-3/2
p=37/10=3.70
Therefore,pucks cost $3.70 and sticks cost $1.50
Answer:
It would have to be cup C.
All right angle triangles have perpendicular lines
To convert from a percentage to a decimal, move the decimal twice to the left
11% = 0.11
200% = 2.00
20.07% = 0.2007
198.4% = 1.984
Hope this helps!
Answer: 5/12 of the whole pizza

Then he ate 3/8:
1 - 3/8
And then 2/3 of what was left:
2/3(1 - 3/8)
2/3 - 1/4
8/12 - 3/12
5/12
