Your friend thinks that the equation k-3.5=21 is a true statement. Is your friend correct? Explain
No, your friend is not correct. The equation k-3.5=21 is not a true statement because it does not have a definite answer. In order for the equation to be true, k would need to be equal to 24.5.
To determine whether the equation k-3.5=21 is a true statement, we need to solve for the variable k.
To do this, we should isolate the variable on one side of the equation.
Start by adding 3.5 to both sides of the equation:
k - 3.5 + 3.5 = 21 + 3.5
This simplifies to:
k = 24.5
Now we can check if the statement is true by substituting the value of k back into the original equation:
24.5 - 3.5 = 21
The left side of the equation simplifies to:
21 = 21
Since both sides of the equation are equal, we can conclude that the statement is true. Therefore, your friend is correct in thinking that the equation k-3.5=21 is true.
To determine whether your friend's statement is correct, we need to solve the equation and check if the solution satisfies the equation.
First, let's isolate the variable by adding 3.5 to both sides of the equation:
k - 3.5 + 3.5 = 21 + 3.5
This simplifies to:
k = 24.5
Now we have the value of k as 24.5.
To verify if this solution satisfies the equation, substitute k = 24.5 back into the original equation:
24.5 - 3.5 = 21
This simplifies to:
21 = 21
Since both sides of the equation are equal, we can conclude that the statement is true. Therefore, your friend is correct in believing that the equation k - 3.5 = 21 is true.
