Question

Answer these 4 for me please help me step by step

Answer 1

4.

The equation we have is:

`(8)/(5)a=-6`

To solve for "a", we want to isolate it in one side.

For this. we can start by multiplying each side by 5. This will make the denominator to cancel out:

`\begin{gathered} 5\cdot(8)/(5)a=5\cdot(-6) \\ 8a=-30 \end{gathered}`

Now, we can divide both sides by 8, which will cancel the coefficient 8 multiplying "a":

`\begin{gathered} (8a)/(8)=-(30)/(8) \\ a=-(15)/(4) \end{gathered}`

And that is the answer to 4.
