Each of the numbers 10, 70 and 490 is separated from the next by a factor of 7. 10 times 7 is 70; 70 times 7 is 490; 7 times 490 is what? 7 times 7 times 490 is what?
You multiply both sides by 9 first so you have -45=y-7. then add 7 to both sides to get y=-38
700*6=4,200
<em>*4,200 as an estimate.</em>
---------------------------
6*(758)
=6(700+50+8)
=4,200+300+48
=4,200+348
=4,548
