You are looking for the shaded region that would be contained in both of the inequalities.

You have:
$x+y \leq 80$ $5x+10y\ \textgreater \ 500$

If you graph an shade the correct half-plane for those equations, you will see there is a triangular region on the left side of the first quadrant.

413 divided by 14 <br> How do you it?

guajiro [1.7K]

You can either do this on the calculator, or in your head. As its a larger number, it is worth doing it on the calculator.
413/14= 29.5
The alternative method is to list all of the tens multiples, and the smaller multiples when you're getting close to the answer, and this will be able to help you.
14x10= 140
14x20=280
14x30= 420 (which is slightly too big)
14x29= 406 (slightly too small)
14x29.5= 413

Hope this helps :)
