Just take the parenthesis and you will have your answer.
7x = 21 x = 3
It is -15x2 + x - 21.
minus eight 13 - (-23) - (180 / 45) + (-40) = -8 That's assuming that the 180 was to be divided by 45 (its hard to write parentheses in text!) The above answer is correct if you are following the standard Order of Operations, which are: 1. Exponents and Roots 2. Multiplication and Division 3. Addition and Subtraction See the Related Links for more info on Order of Operations. Another answer: I read it as: {[13-(-23)-180]/45} + -40 = -43.2 I divided first three numbers by 45, not just 180. That's just how I read it.

23 + 10 - 12 = 21
-21.. (or minus 21)
23 + 21 = 44
Minus 4.
No, 21- (5 plus 2) does NOT equal 23.
27 times 3 minus 46 plus 23 equals 58.
Jan = 23 minus one day for New Years = 22 Feb = 21 March = 21 April = 22 May = 22 minus one for Memorial day = 21 June = 21 July = 23 minus one day for the 4th = 22 Aug = 21 Sept = 22 minus one for Labor Day = 21 Oct = 23 Nov = 20 minus one for Thanksgiving = 19 Dec = 23 minus one for Christmas = 22
23 + 56 - 4 = 75
62

C+ (-2)= 21= 21+2= 23+ (-2)= 21 23+ (-2)= 21 is the same as 23- 2= 21
