What is the solution to the equation fraction 4 over 5 n minus fraction 1 over 5 equals fraction 2 over 5 n?

Equation: (4/5)n - 1/5 = (2/5)n

Steps:

1. ((4/5)n - 1/5) - (4/5)n = ((2/5)n) - (4/5)n

2. -1/5 = -2/5n

3. -1/5/-2.5 = -2/5n/-2.5

Solution: n = 2/25 or 0.08

n = 0.5

Step-by-step explanation:

Equation according to given data:

                                                           (4/5)n - 1/5 = (2/5)n

Solution:

(4/5)n - 1/5 = (2/5)n

Subtracting (4/5)n on both sides of equation:

= (4/5)n - 1/5 - (4/5)n = (2/5)n - (4/5)n

= - 1/5 = -2/5n

Multiplying -5/2 on both sides of equation:

= -1/5 . -5/2 = -2/5n . -5/2

= 5/10 = n

= n= 1/2 = 0.5

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
