Answer:
-10
Step-by-step explanation:
Okay, let's break this down.
We've got the expression [tex]-\frac{1}{3}(12+18)[/tex]. We have to use the distributive property on this because we must multiply all terms inside the parentheses (12 and 18) by [tex]-\frac{1}{3}[/tex].
If we are multiplying by a fraction it's the same as dividing by the denominator.
So to simplify this we need to do [tex](12\div -3+18\div -3)[/tex]
12 divided by -3 is -4
18 divided by -3 is -6
So we now have [tex]-4-6[/tex]. This equals -10.
Hope this helped!
