Answer:
5.79 feet
Step-by-step explanation:
Let us represent
First piece = x
Second piece = y
Third piece = z
Sac had a rope that was 15 feet long.
x + y + z = 15
He cut it into three pieces.
The first piece was 3.57 feet longer than the second piece.
x = 3.57 + y
The third piece was 2.97 feet longer than the second piece.
z = 2.97 + y
How long was the third piece of rope?
x + y + z = 15
3.57 + y + y + 2.97 + y = 15
3y + 6.54 = 15
3y = 15 - 6.54
3y = 8.46
y = 8.46/3
y = 2.82 feet
Therefore, the length of the third piece z = 2.97 + y
z = 2.82 + 2.97
z = 5.79 feet

Answer:
$496800
Step-by-step explanation:
You need to find 3.5% of 480,000 and then add it to 480000:
You convert 3.5% to 0.035 (divided by 100).
Now you multiply 0.035 * $480,000 = $16800 (this is the amount of money to add to the value of the house)
Total value of the house: $480,000 + $16,800 = $496800
Technically, you could go through and add every single integer between -102 and 104, but that is a lot of work.
However, there is a shortcut.
The opposite of -102 is 102, right? When you add two opposites together, they turn out to be 0. You can use this for every integer from -102 to 102.
Basically, you end up with 103 and 104 that are left.
Add them and you get 103+104=207.
207 is the answer.
