Answer:
8/3 = 2 2/3
Step-by-step explanation:
(2/7)y + (3 1/7)y = (3 3/7)y = (24/7)y
For y=7/9, this is ...
(24/7)(7/9) = 24/9 = 8/3
The value of the expression for y=7/9 is 8/3.
The reciprocal of any number is the other number you must multiply it by to equal one. In this case it's 9/2
Answer:
Let b = rate of the boat.
Let r = rate of the river.
The rate going downstream is b + r.
The rate going upstream is b - r.
rate x time = distance
4(b + r) = 144 ---> b + r = 36 [divide both sides by 4]
9(b - r) = 144 ---> b - r = 16 [divide both sides by 9]
Add town: 2b = 52
Divide by : b = 26 mi/hr
r = 10 mi/hr
