5.
-0.9p+3.2=-1.7p
subtract add 0.9p to both sides
3.2=-0.8p
divide both sides by -0.8 to isolate p
-4=p
6.
-14.3=-1.4-3d
add 1.4 by both sides
-12.9=-3d
divide both sides by -3 to isolate d
4.3=d
Answer:
the answer is 48:34
Step-by-step explanation:
82 - 48 = 32
so 48 : 32
108=3(b-s)
36=b-s
s=b-36
...
108=2(b+s), and using s found above gives us:
54=b+b-36
54=2b-36
2b=90
b=45, and since s=b-36, s=9
So the boat's speed is 45mph and the stream's speed is 9mph
