Best ResponseYou've already chosen the best response.0Imagine if the variable x were to be equivalent to 1 or 2. Input that into 10x (giving you 10 or 20) then try that same method on the answer choices and the answer will be the one that matches your 10x :)

Best ResponseYou've already chosen the best response.0a number divided by itself would be 1 so x/x would become 1 times what ever else was attached to it and there would be no x left ("a" cough)

Best ResponseYou've already chosen the best response.8Well you are mostly right. You seem to get this :) dont be so critical. what I am trying to say is variables divide out. Exponent rules: \[x^{0} = 1\] anything to the power of 0 is equal to 1 \[x^{1} = x\] \[x^{2} = x*x\] \[x^{3} = x*x*x\] etc \[x^{a}x^{b} = x^{a+b}\] \[\frac{x^{a}}{x^{b}} = x^{a}x^{b} = x^{a + (b)} = x^{a  b}\] \[x^{1} = \frac{1}{x^1} = \frac{1}{x}\] \[\frac{1}{x^{1}} = x^{1} = x\] Examples: \[\frac{34x^2}{x} = 34x\] \[x^5x^3 = x^{5+3} = x^{8}\]

Best ResponseYou've already chosen the best response.8more examples: anything raised to the power of 0 is 1: \[(3 + x + 3b)^{0} = 1\] \[\frac{(3+x)}{x+2} = (3+x)(x+2)^{1}\]

Best ResponseYou've already chosen the best response.0@thatgirlaggie Reconsider choice A 50x/5x can be rewritten as (50/5)*(x/x) as mentioned, (x/x)=1 and since 50/5 = 10 (50/5)*(x/x) would equal 10 (no x)

Best ResponseYou've already chosen the best response.8your answers are: \[\frac{50x}{5x}\] \[\frac{50x}{5}\] \[(\frac{50}{5})x\] Multiplication of fraction rule: Note you can divide anything by 1 to make it into a fraction: \[x = \frac{x}{1}\] example: \[62 = \frac{62}{1}\] Multiplication of fractions rule: \[\frac{a}{b}*\frac{b}{c} = \frac{a*b}{b*c}\] example using both \[\frac{52x}{3}*52 = \frac{52x}{3}*\frac{52}{1} = \frac{52x*52}{3*1}\]

Best ResponseYou've already chosen the best response.8I am giving you rules so you can do these problems I hope that you take the time to review them, it should help you quite a bit, note a, b an x are all just numbers

Best ResponseYou've already chosen the best response.8But yes the answer is D and E \[\frac{50x}{5x} = 10*x^{11} = 10*x^{0} = 10 \neq 10x\]

Best ResponseYou've already chosen the best response.0so because A has two x's, there are only two answers?

Best ResponseYou've already chosen the best response.8the x cancels out in one of them and you end up with just 10
