X➝-x by reflection, so g(x)=-x
The original price was $25.
First, convert the 30% to a real mathematical number. For percents, this is always done by dividing the 30% by 100%, or 30% / 100% = 0.300.
Second, find out what 30% of $25 is. This is the amount of the sale discount. This is always found by mulitplying 0.300 by the item's cost $25, like this:
0.300 x $25 = $ 7.50.
So for this sale, you'll save $ 7.50 on this item.
This means, the cost of the item to you is
<span>$25 - $ 7.50 = $17.50.</span>
Yes I think it really is the correct answer
Answer:
3 3/5 =x
3 .6 =x
Step-by-step explanation:
6/5 = x/3
Use cross products

18/5 = 5x/5
18/5 =x
3 3/5 =x
First write nine ten thousands in standard form which is 90,000. Next divide 90,000 by 10 and you should get 9,000 by crossing out one zero in both numbers. To get 9,000 in unit form all you have to write is 9 thousands. And your answer is 9 thousands
