Answer by pwac(253) (Show Source):
You can put this solution on YOUR website!
are your expressions 5r and?
If so,when r=6
5r means replace the r with 6 so you have
5 x 6 which =30.
With this becomeswhich =3.
In your next question
7x2>3m.All this means is which of the given numbers when multiplied by 3
is less than 7x2 which is equal to 14
start with m=4. 7x2>3x4 = 14>12. so we have hit on it straight away.
If m = any of the other given numbers these would make 3m bigger than 14
so m=4 is the correct answer.
Hope you understand.
