Best ResponseYou've already chosen the best response.1\(\large\color{black}{ \displaystyle (23)\times(24)=(1)^2\times 23\times 24=23\times 24 }\) I am just showing that for all positive number a and b, when you say: `(a)•(b)`, that will be the same as `a•b`.

Best ResponseYou've already chosen the best response.0Yes, and I had tht on paper but i dont understand why i didnt get that when i drew it out on paper lol

SolomonZelman

Best ResponseYou've already chosen the best response.1maybe because you counted the 1 on top of the 2 in 23 twice.

Best ResponseYou've already chosen the best response.1I am not sure how you got 652, but as long as you understand everything now, we are good

Best ResponseYou've already chosen the best response.1That symbol is division I suppose?

Best ResponseYou've already chosen the best response.1\(\large\color{black}{ \displaystyle 6.9~\div~0.03 }\)

SolomonZelman

Best ResponseYou've already chosen the best response.1Say you have some fraction: \(\large\color{black}{ \displaystyle \frac{A}{B} }\) So you can multiply top and bottom by some number, and the value doesn't change. In other words, \(\large\color{black}{ \displaystyle \frac{A}{B}=\frac{A\times x}{B\times x} }\)

SolomonZelman

Best ResponseYou've already chosen the best response.1Similarly, in our case: \(\large\color{black}{ \displaystyle \frac{6.9}{0.03}=\frac{6.9\times 100}{0.03\times 100}=\frac{690}{3} }\)

Best ResponseYou've already chosen the best response.1I am sure you can divide 690 by 3 in your head, without even involving a paper.

Best ResponseYou've already chosen the best response.0Most of it I know so I'll just post the ones i need help on.

SolomonZelman

Best ResponseYou've already chosen the best response.1do that and then add the negative sign to the result

SolomonZelman

Best ResponseYou've already chosen the best response.1Yes, that is right

SolomonZelman

Best ResponseYou've already chosen the best response.1remember that I said (a)•(b) is same as just a•b? Same applies to division: That is, (a)÷(b)=a÷b so what is 84÷12 ?

SolomonZelman

Best ResponseYou've already chosen the best response.1Oh, these are absolute value bars

SolomonZelman
 one year ago
Best ResponseYou've already chosen the best response.1Absolute value, one way to think of it: Say you have: "aboslute value of a" which is written as a dw:1440473268072:dw

SolomonZelman

Best ResponseYou've already chosen the best response.1so if you have a then it will be also positive a.

anonymous

Best ResponseYou've already chosen the best response.0Ohhhh Now I get it. i NEVER knew what those were

SolomonZelman

Best ResponseYou've already chosen the best response.1But, absolute value is not relevant to the actual question tho'. Your balance after you spent 7$ more than what you had is 7 dollars less, and that is represented by 7.

SolomonZelman
 one year ago
Best ResponseYou've already chosen the best response.1It is not just 7, or not 7 or 7, because spending more than what you have is a negative 7 dollars on your account.
