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

Step-by-step explanation:
Hello, let's say that her departure trip takes t in minutes, as her return speed is 3 times her departure speed, she took t/3 for the return and we know that this 40 minutes less, so we can write.
t/3=t-40
We can multiply by 3
t = 3t -40*3 = 3t - 120
This is equivalent to
3t -120 = t
We subtract t
2t-120 = 0
2t = 120
We divide by 2
t = 120/2 = 60
So this is 60 minutes = 1 hour.
Thank you.

Answer:
8 7/24
Step-by-step explanation:
These are mixed fractions first you need to convert them
4 5/8= 37/8
3 2/3= 11/3
Take LCM of 3 and 8 which 24.
Multiply 37/8 with 3= 111/24
Multiply 11/3 with 8= 88/24
Now add both fractions
111/24 +88/24 =199/24
This is an improper fraction. Divide 199 by 24 to change this into mixed fraction
8 7/24
