Determine whether the given value is a solution of the equation(is this a YES or NO)
1 answer:
To determine if a given value is a solution of the equation, we will substitute the given value in for the variable it has been assigned to.
In this equation, our variable is k.
Substitute 5 in for k:
Now we will simplify the right side of the equation:
25 = 1
25 does not equal 1, so we know that the given value 5 is not a solution for the equation.
In this equation, our variable is k.
Substitute 5 in for k:
Now we will simplify the right side of the equation:
25 = 1
25 does not equal 1, so we know that the given value 5 is not a solution for the equation.

Answer:
It takes <em>10 minutes</em> to the park.
Step-by-step explanation:
Given that:
Time taken = 6 minutes
Distance left to be traveled = 40%
To find:
The equation to represent the distance , that still needs to be traveled after
minutes.
Solution:
As per given statement, distance traveled in 6 minutes = 60%
We can say that:
Distance traveled each minute = = 10%
After 1 minute, distance traveled = 10%
Distance left = 100 - 10 = 90%
After 2 minutes, distance traveled = 20%
Distance left = 100 - 20 = 80%
After minutes, distance traveled = 10
%
Distance left, = (100 - 10
)%
Therefore, the equation is:
Time taken by the bike to reach to the park can be found by putting = 0 (i.e. distance left to be traveled = 0)
