L = 4D + 54 <== ur equation
the crew worked for 31 days...so sub in 31 for D
L = 4(31) + 54
L = 124 + 54
L = 178 miles <==
Answer:
ruler(×,y)=(20,20)
Step-by-step explanation:
sorry if its wrong
anyways are you using a mac?
We calculate both velocities:
upstream 8 miles in 2 hours = 4 miles / hour
downstream 8 miles in 1 hour = 8 miles / hour
ps -stream speed = 4 mph
ps + stream speed = 8 mph
Adding both equations
2 ps = 12 mph
paddling speed = 6 mph
stream speed = 2 mph
They are vertical angles. They are congruent.
(2x+2)= (3x-52)
Add 52 to the other side.
2x+54=3x
Subtract 2x on both sides.
54=x
I hope this helps!

Answer:
It would be 20
Step-by-step explanation:
because 5x+20 = 5x + <u> </u>
