5. Write an equivalent expression for3(0.2y - 0.8).

Answer :

We can find an equivalent of the expression:

[tex]3\cdot(0.2\cdot y-0.8)[/tex]

applying the distributive property for the multiplication:

[tex]3\cdot(0.2y-0.8)=3\cdot0.2\cdot y-3\cdot0.8=0.6\cdot y-2.4[/tex]

So the answer is: 0.6y - 2.4
