  1. Determine which inequality is not correct ?

    $ -1<-2$

    $ 5<y<100$

    $ 2<x<5$

    $ 3<4<5$

  2. Write the expression $ \vert\pi-4\vert+\vert x-5\vert$, if $ x<2$ without absolute value bars and simplify.

    $ -\pi+1-x$

    $ \pi+x-9$

    $ 9-\pi+x$

    $ 9-\pi-x$

  3. Evaluate the expression $ \vert 2-3\vert+ (5+2)^2$:

    $ 48$

    $ 10$

    $ 28$

    $ 50$

  4. Let $ x=-4$, and $ y=2$. Evaluate the expression $ \frac{4\vert x\vert+4\vert y\vert}{\vert x\vert}$:

    6

    5

    2
