6p + 1m = $9<br><br> 4p + 2m = $8
Monica [59]
You can multiply 6p + m = 9 by -2 so you gonna have -12p - 2m = -18 then you can say : -12p - 2m = -18 ⇒ -8p = -10 ⇒ p = 10/8 ⇒ p = 1.25  
                 4p + 2m = 8 
so now you can find the m : 6 * 1.25 + m = 9 ⇒ 7.5 + m = 9 ⇒ m = 9 - 7.5 ⇒ m= 1.5 :)))
i hope this is helpful 
have a nice day

If n is a rational number then n2 is always less than n
stiv31 [10]

That easiliy false. You can prove this by observing that all integers are, in particular, rational numbers. So, for instance, you can think of 4 as \frac{4}{1}, so 4 \in \mathbb{Z}\subset\mathbb{Q}

And obviously, you have 4^2=16>4

It is true that the square of every rational number between 0 and 1 is smaller than the number itself.

But since not all rational numbers are between 0 and 1, the general claim is false.
