Answer: n=15
Step-by-step explanation:
To find the perimeter, you add all of the side lengths together. This would make the equation 28+28+n+n. You already know the perimeter and are trying to find n. Your new equation is 28+28+n+n=86
You would then combine the like terms and get
56+2n=86
Then you would subtract 56 from both sides and get
2n=30
Finally, you want to divide both sides by 2 in order to get n alone. 30/2 is 15. Therefore,
N=15

Answer:
Step-by-step explanation:
Given
<em>468 and 241</em>
Required
<em>Sum of the Tens</em>
Breaking 468 to smaller bits; we have
Hundred = 400
Tens = 60
Units = 8
Breaking 241 to smaller bits; we have
Hundred = 200
Tens = 40
Units = 1
The question requests for the sum of the Tens;
The sum of the tens goes thus;
Hence, the sum of tens of 468 and 241 is 100
