Answer:
The answer to your question is below
Step-by-step explanation:
People need to know how to convert units because variables are measured in different units and it is necessary to know the equivalence to know if people is talking about the same thing.
For example, if we measure our height in feet and somebody measure his height in meters, we need to know how to convert units to know the exact height of this person.
Or if our currency is dollar and we travel to a country with a different currency, we must know how to convert units to know the price of something in a different country.
In a fraction, the numerator is the number on the top.

Answer:
The value of x is 16
Step-by-step explanation:
The angle Bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle
In Δ QPR
∵ QS is the angle bisector
∵ PR is the opposite side
→ By using the rule above
∴ =
∵ PS = x and PQ = 30
∵ PR = 40
∵ RS = PR - PS
∴ RS = 40 - x
∵ RS = 40 - x and RQ = 45
→ Substitute them in the rule above
∴ =
→ By using the cross multiplication
∵ x × 45 = 30 × (40 - x)
∴ 45x = 30(40) - 30(x)
∴ 45x = 1200 - 30x
→ Add 30x to both sides
∵ 45x + 30x = 1200 - 30x + 30x
∴ 75x = 1200
→ Divide both sides by 75
∴ x = 16
∴ The value of x is 16
