Before the 17 and after the 10, but they aren't necessary.
The parentheses would be placed thus: 27 - (49 / 7 + 12) = 8
As there are no parentheses then the expression stated can be simplified as follows :- 7x - 4x - 9 = 3x - 9 If the parentheses were placed (7x - 4x) - 9 then the result would be the same. If the parentheses were placed 7x - (4x - 9) = 7x - 4x + 9 = 3x + 9.
around the 8 and the 5
Limitations in the WikiAnswers database do not allow certain characters to be used in questions. Also, we would be reluctant to add commas to questions, as parentheses would allow many different variations of a question to be asked. See Related Question.
In general, the period goes within the parentheses (I really wasn't sure it was a good idea.) My paranthetical sentence was just an example ... but I am not sure what you mean by imcomplete thought...... then you would end with ...
(200-90)+20=10
2+(4+7)= 2+10= 12 so, the answer is twelve the correct way to say that arithmetic problem would be..... two plus the quantity four plus seven
If you would like me to answer your question, I would wish for you to word your question better.
the question is 2-5(h+3)=-28. and i know that h=3but im not sure how you would solve this problem
10(2.1) + 5(12.2) = 10*2.1 + 5*12.2 = 21 + 61 = 82
The first thing I would do would be to multiply the decimal by itself, then write theresult inside the parentheses, get rid of the original decimal in there, and throw awaythat little 2 after the parentheses.
The answer would be 30 - 4 x (2 +5) = 2 Because 30 - 28 = 2
