solve using the multiplication principle:
-7x > 1/15 (yes that is a fraction and that is what is confusing me)
I'm not too sure what the multiplication principle is, but does it refer to cross-mutiplying?
i.e.
$\displaystyle \frac{-7x}{1}>\frac{1}{15}$
$\displaystyle -105x>1$ (from cross-multiplying)
$\displaystyle x<-\frac{1}{105}$
Sorry if I misunderstood the question.
Hi,
My name is Paul and I'm in class 5...sorry 'cuz I posted in this thread but...something is entangling me...sorry if I'm writing wrong 'cuz I'm from Romania...I don't know if this is harmonize with the thread but...1x2x3x...x20...how to resolve???
If can someone help me
THANKS!!!
Create a new thread, please ...
By the way, what do you mean by "resolve" ? The expression you just gave us is the factorial of $\displaystyle 20$, written $\displaystyle 20!$. Most calculators have a factorial key to compute it quickly. This way, $\displaystyle 20! = 2432902008176640000$.
