Solve for k: 4.95 = 0.4 + k
Understand the Problem
The question asks to solve the equation 4.95 = 0.4 + k for the variable k. This involves isolating k to find its value.
Answer
$k = 4.55$
Answer for screen readers
$k = 4.55$
Steps to Solve
-
Isolate k To isolate $k$, we need to subtract $0.4$ from both sides of the equation. $$4.95 = 0.4 + k$$
-
Subtract 0.4 from both sides Subtracting $0.4$ from both sides, we get: $$4.95 - 0.4 = 0.4 + k - 0.4$$
-
Simplify the equation Simplifying the equation gives us: $$4.55 = k$$
-
Final Answer Therefore, $$k = 4.55$$
$k = 4.55$
More Information
The variable $k$ represents an unknown number. In this problem, $k$ is equal to $4.55$, which makes the original equation true: $4.95 = 0.4 + 4.55$.
Tips
A common mistake is to add $0.4$ to $4.95$ instead of subtracting it. Remember to perform the opposite operation to isolate the variable.
