"a congruent to b mod H" just means they both have the same remainder when divided by H.  e.g. 12 and 27 mod 5:  each of them when divided by 5 leaves remainder 2.\n\nThe word "arbitrary" means you just make it up or pick it -- it isn't derived by any rule.\n\nabelian means commutative:  i.e. when the operation which is part of the definition of the group is performed on two members, order doesn't matter.  e.g. the set of integers under addition is abelian because \nm + n = n + m, but the set of integers under subtraction (actually I don't think that's even a group!!) isn't abelian because \nm - n is not equal to n - m.\n\nI don't know.  Exactly what symbols do you mean?  Use words if you can't get the symbol on the keyboard.

simply subtract 7 from both sides. This leave you with\n\nx<_3

(1) First one is copied wrongly by you                                            (2) Where is the equal to sign?                                                        (3)This equn. also cannot be solved                                              (4)-p/16+5=9  Multiplying all the terms by 16 ,we get -p+80=144   =>-p=144-80=66 Therefore p=66 YOU SHOULD BE MORE CAREFUL BEFORE SENDING YOUR PROBLEMS TO YAHOO ANSWERS.HOWEVER,YOU MAY SEND THE CORRECTED VERSION OF THE PROBLEMS TO ME IMMEDIATELY THROUGH YAHOO ANSWERS.

16/24....it's really not that hard...you should be able to solve it on your own.\nps. you might want to simplify it down to 2/3.

Your computer has a calculator built in.  Failing that, try long division.  You're gonna have to learn how to do it anyway.\n\nSheesh.

Subract the two terms on the left giving:\n-2t < 16\n\nAdd 2t to both sides giving\n0 < 16 + 2t\n\nSubtract 16 from both sides\n\n-16 < 2t\n\nDivide both sides by 2\n\n-8 < t

Q = m * Cp * DeltaT.\n\nPlug the numbers in.  Get Cp from your book.
