Answer:
The cost of the diamond last year is x = $ 830
Step-by-step explanation:
Let the cost of diamond last year = x
the cost of diamond present year = y
Given that diamond today cost ten dollars more than twice what it cost last year.
⇒ y = 2 x + 10 ------ (1)
The sum of the cost (last year and this year) is = $ 2500
⇒ x + y = $ 2500 -------- (2)
Put the value of y in equation (2) from equation (1), we get
⇒ 2 x + 10 + x = $ 2500
⇒ 3 x = 2490
⇒ x = $ 830
& y = 2500 - 830
⇒ y = $ 1670
Therefore the cost of the diamond last year is x = $ 830

Below is the complete solution :
-
two points on earth are :
(39N,120W) and (41N,84W)
midpoint between them = <span>(<span><span>39+41/</span>2</span>N, <span><span>120+84/</span>2</span>W)
= </span>(802N, 104/2W)
= <span>(40N,52W<span>)</span></span>

The statement that best describes Georgia’s Barrier Islands is; A: They protect the coastline during storms.
<h3>What is the correct statement about the place?</h3>
Barrier islands are called “barrier islands” due to the fact that they are good means of creating barrier between the mainland and the ocean.
Now, these barrier islands tend to shelter and protect the mainland from the powerful forces of wind, waves, and other natural disasters. This they do by;
- Sheltering the estuaries that form behind the barriers.
- Allowing marshes to build up in the quiet waters of the sound.
- Filtering of the pollutants that come in from mainland rivers by the marshes.
- Providing valuable habitats for water animals and others in that ecosystem.
- Serve aesthetic purposes
Barrier islands are a very much valuable resource. Despite the fact that they constantly change and may become badly eroded, they can still rebuild if left alone.
Thus, we can conclude that statement best describes Georgia’s Barrier Islands is that they protect the coastline during storms.
