$10c-f=-13+cd\ \ \ |add\ f\ to\ both\ sides\\\\10c=-13+cd+f\ \ \ \ |subtract\ cd\ from\ both\ sides\\\\10c-cd=f-13\\\\c(10-d)=f-13\ \ \ |divide\ both\ sides\ by\ (10-d)\\\\\boxed{c=\frac{f-13}{10-d} }$

explain how the position of the decimal point changes in a quotient as you divide by increasing powers of ten

olga55 [171]

So we need to see how does the decimal point change it's place in the quotient when we divide any number by increasing powers of 10. Lets start with number 1. The decimal point is: 1.0 and when we divide by 10^1=10 we get 1/10=0.1. The decimal point has moved one place to the left. Now lets divide 1 by 10^2 and we get 1/100=0.01. Again, the decimal point has moved one more place to the left. Now: 1/10^3 = 1/1000 = 0.001. Next would be 0.0001, next one would be 0.00001 and so on.
