If

then using the chain rule, we have


Then

If g=guppy, go=goldfish, b=bettafish and a=angelfish we can set up expressions for each set of fish.
1g=3go
1go=2b
1b=2a
By working backwards and substituting we can finally work out 1 guppy to be equal to 12 angelfish.
The formula for the area of a parallelogram is
A=b*h where b=base and h=height
plug in the data we know
A=4*5.5
A=22m²
Answer=B
I believe it’s SAS. I hope I’m right
65+50x = 55x + 20
-50x -50
65=5x+20
- 20 - 20
55=5x
55/5= 5x/5
11=x
The solution represents that it 11 months will make both gyms the exact same price.
