A. 2x+y=25; x+y=20
x represents cheese wafers and y represents chocolate wafers.
B. I will choose elimination since there is y and y. I can multiply one equation by -1 to get y and -y, which cancels out.
2x+y=25
-x-y=-20
Add equations
x=5
Plug x in
5+y=20
y=15
Final answer: 5 cheese wafers, 15 chocolate wafers
Answer:
<em>C. 1/60</em>
Step-by-step explanation:
Probability of 3 on a cube: 1 / 6
Probability of 9 from cards 1-10: 1/10
1/6 x 1/10 = 1/60
Answer: Its c 8-10
Step-by-step explanation:
Answer: 13.5 hours or 14 hours (if you round it)
Step-by-step explanation:
* 15
=13.5
1500 + 125h = 2125 subtract 1500 from both sides
125h = 625 divide by 125
h=5
5 hours is the max amount of time
