81^5 = 3,486,784,401
3,486,784,401 / = X
X = 1,162,261,467
(I think anyways)
Answer:
Klorina's rate in still water is 4.5 km/h
Current's rate is 0.5 km/h
Step-by-step explanation:
Let
x km/h = Klorina's rate in still water
y km/h = current's rate
<u>With the current (current helps):</u>
Distance = 10 km
Time = 2 hours
Rate = x + y km/h

<u>Against the current:</u>
Distance = 8 km
Time = 2 hours
Rate = x - y km/h

Divide both equations by 2:

Add these equations:

Subtract these two equations:

Answer:
2 1/14
Step-by-step explanation:
First, we will equalize the denominators of the fractions.
(1/7) × 2 = 2/14
Then we can solve this equation.
2 2/14 - 1/14 = 2 1/14
Answer:
Anthony is incorrect
According to the order of operations(PEMDAS), you must first multiply 10 × 3
which equals 30, then you add 2, which equals 32, finally you subtract 2, which brings you back to 30
10 × 3 = 30
2 + 30 - 2 = 30
