Answer:
The value of x is 5
Step-by-step explanation:
In the given triangle
∵ A segment joining two points lie on the two side
∵ This segment is parallel to the third side
∴ This segment divides the two sides into parts that have the same ratio
→ That means x over 2x - 3 equal to 10 over 14
∵ =
→ By using cross multiplication
∴ 10 × (2x - 3) = x × 14
∴ 10(2x) - 10(3) = 14x
∴ 20x - 30 = 14x
→ Add 30 to both sides
∵ 20x - 30 + 30 = 14x + 30
∴ 20x = 14x + 30
→ Subtract 14x from both sides
∵ 20x - 14x = 14x - 14x + 30
∴ 6x = 30
→ Divide both sides by 6
∴ x = 5
∴ The value of x is 5

Answer:
The elevation when the boiling point of water is °
is 12790.70 feet
Step-by-step explanation:
Let every 1,000 feet of elevation be . Hence, we can write
Where is the boiling temperature of water at different elevations
Now, to the determine the elevation when the boiling point of water is °
.
We will determine by putting
°
.
Hence,
Since represents every 1,000 feet of elevation, then the elevation when the boiling point of water is
°
×
feet
Hence, the elevation when the boiling point of water is °
is 12790.70 feet
