Textbook Question #28

Thursday, November 5, 2009
Okay 905! I mean *the class* Here is question #28 in extend.

Okay so I'm going to do each letter separate.
So A) First you replace the Y's with -0.5 because it says that
y= -0.5.

Second. BEDMAS do the brackets 2x-0.5

Third. ADD.

YA one part done. Now B) First replace the M's, with 1.7

Second BEDMAS brackets first.

Third. Multiply.

Almost Done. C) First replace the Q's with -3.6

Second. First I thought that you subtract fractions, but then i remembered that we haven't learned how to subtract fractions THIS year yet.
So you divide the decimals. 4.5/ -3.6 - -3.6/4.5

Third. You subtract.

Okay so there it is. Sorry for it being so long. Comment please.
