Combine like terms to create an equivalent expression.

Juli2301 [7.4K]

<h2>Answer:</h2>

$\boxed{15.4z-12}$

<h2>Explanation:</h2>

Here we have the following expression:

$7.4z-5(-1.6z+2.4)$

We combine like terms in order to simplify expression. To do so, we combine terms with the same variable and exponents. In this exercise, let's apply distributive property first:

$7.4z-5(-1.6z)-5(2.4) \\ \\ Remember \ these \ rules: \\ \\ (+)(+)=+ \\ \\ (-)(-)=+ \\ \\ (-)(+)=+ \\ \\ (+)(-)=- \\ \\ \\ So: \\ \\ 7.4z+8z-12 \\ \\ \\ Combining \ like \ terms \ 7.4z \ and \ 8z: \\ \\ \boxed{15.4z-12}$
