Question

simplify the expression.
-2.2f + 0.7f - 13 - 6

-2.2f + 0.7f - 13 - 6 = \square
(simplify your answer. use integers or decimals for any numbers in the expression.)

Explanation:

Step1: Combine like terms for f

To combine \(-2.2f\) and \(0.7f\), we add their coefficients. The coefficient of \(-2.2f\) is \(-2.2\) and the coefficient of \(0.7f\) is \(0.7\). So, \(-2.2f + 0.7f = (-2.2 + 0.7)f\). Calculating \(-2.2 + 0.7\) gives \(-1.5\). Thus, \(-2.2f + 0.7f = -1.5f\).

Step2: Combine constant terms

Now, we combine the constant terms \(-13\) and \(-6\). Adding \(-13\) and \(-6\) gives \(-13 - 6 = -19\).

Step3: Combine the results

Putting the two results together, we have \(-1.5f - 19\).

Answer:

\(-1.5f - 19\)
