So it says 8 less than, meaning 8 minus the product of 5 and -4, so literally it means subtract 8 from 5X-4
8-5*-4
❄ Hi there,
let us start by considering this: What should we do to get x all by itself?
Since it's
- divided by 4
- multiplied by -1
we should
- multiply (both sides) by 4
- divide (both sides) by -1
So, let's start.


When we divide both sides of an inequality by a negative number, we do "the inequality flip" and <em>flip the inequality sign</em>.

The perimeter is all sides length added together. You can make an equation:5+5+x+x where x is the length.
5+5=10 18-10=8 There is two sides so you do eight divided by two
The length is 4
I got a. I multiplied 0.125 by 45 and got 5.625. I then divided 5.625 by five an got 1.125. I'm not really sure about my answer, so I did it another way. I divided .125 by five and got .025 so I multiplied that by 45 and got 1.125. I multiplied 1.125 by 1000 and got A.
