Answer:
SO THE AWNSER WILL BE (B)
Step-by-step explanation:
x − y = 7
y = 3x + 12
a
2 over 19 comma 2 over 33
b
negative 2 over 19 comma negative 33 over 2
c
negative 19 over 2 comma negative 33 over 2
d
19 over 2 comma 33 over 2
SO THE AWNSER WILL BE (B)
210, 420, 630, 840
multiples of 2*3*5*7
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
Step-by-step explanation:
2-5(68-60)=2-5×8=2-40=38
