Question

Which expression is equivalent to  0.9+k-0.54 k ?  0.46 k+0.9  1.36 k  -0.64 k  1.9-0.54 k

Bytelearn · Accepted Answer

Combine Like Terms: Combine like terms by adding the coefficients of k. We have k and -0.54k which are like terms. To combine them, we add their coefficients: 1 (the coefficient of k when it's not written is 1) and -0.54. Calculation: 1 + (-0.54) = 0.46Rewrite Expression: Write the expression with the combined like terms. Now that we have combined the coefficients of k, we rewrite the expression with the new coefficient for k. Expression: 0.9 + 0.46kCheck Answer Choices: Check the answer choices to see which one matches the expression we found. We are looking for an expression that matches 0.9 + 0.46k. Checking the answer choices: - 0.46 k+0.9 is the same as 0.9 + 0.46k (since addition is commutative). - 1.36 k does not match because the coefficient of k is different. - -0.64 k does not match because it does not have the constant term 0.9 and the coefficient of k is incorrect. - 1.9-0.54 k does not match because the constant term is different and the coefficient of k is not combined correctly.

Which expression is equivalent to $0.9+k-0.54 k$ ? $\newline$ $0.46 k+0.9$ $\newline$ $1.36 k$ $\newline$ $-0.64 k$ $\newline$ $1.9-0.54 k$
