Sam started with 0 dollars in his bank account. He charged his debit card for a sandwich that costs $6.00. If this was written on a number line. How many units would Sam to go to get back to where he started?
The sum(9) of half of the first number(1/2a) and one third of the second number(+1/3b)
That is correct
.55*X=231 .....X=231/.55.......X= 420
It changes it into negative
