Answer:
Step-by-step explanation:
To find out the sales tax rate, we divide the sales tax by the cost of the item. This will give us what percent of the cost of the item the sales tax is equal to.
So, 20.4 divided by 340 = 0.06
To convert to percent, we multiply 0.06 by 100=6. Therefore, the sales tax rate is 6%.
Check:
340 times 0.06 (the sales tax rate) is 20.4 (the sales tax).
The undefined term that can contain parallel lines are line.
The answer is: " -5/3 " ; or, write as: " -1 ⅔ " .

(-5/6) + (-5/6) = (-5/6) <span>− (5/6) ;
------> {since: "adding a negative" is the same a "subtracting a positive"} ;
------> </span> (-5/6) − (5/6) = (-5 − 5) / 6 ;
= -10/6 = (-10/2) / (6/2) ;
