i think the next number is 731 too. However my way of doing it is by multipling 3 to the number and substract by 4. So 245*3 is 735 and 735-4 is 731.

algebra
another way is... you can substitute the x and try to solve for y. what can 5 go to? 5,10,15,20... so if x=2 then the equation will be 6-5y=25 however -5y cant go to 19 so try another number at the end, you will have x=5 there, 15-5y=25 -5y=10 y=-2 i hope you understand the ...

why does only covalent bond form between two or more nonmetals but not metals?...i am a eighth grader so i am not sure if i need to know them.
January 15, 2008

Science
so...what you mean is that ionic bonds attract (mostly) opposite properties elements and covalent bonds attract similar elements

can you simplify the meaning for the third part too...thanx...because i think i am confusing myself...so the covalent is usually the left side and the ionic are usually on the right side...right?

Science
the first part applies with the polar and nonpolar...so why polar and polar bonds better than polar with nonpolar?
January 14, 2008

Algebra
before you substract, you need to find the common denominator...so the common denominator for 9 and 7 is 63. so you change both into the denominator to 63. there you have 8 7/63-1 54/63 which is 394/64 in improper fraction then you simplify it.
