Answer:
2 s - 4
Step-by-step explanation:
A Regular pentagon means that it has 5 evenly lengthen sides. In other words, the shape with 5 sides has lengths are equal to each other.
Because the total perimeter as mentioned of the pentagon is 10s - 20,
dividing it by 5 should find the length of each side!
Equation: (10s - 20) / 5
Once you finish dividing each digit inside the bracket you are done!
= 2s - 4
So that leaves us with 2s-4
Answer:
2 s - 4

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Case 1: Bus
Consumption/ 100Km= 301
and, for 250 Km= 301 /100 x 250
= 751
Case 2: Car
Total = 80 people
Total cars= 30/5 = 6
Consumption/ 100Km= 91
and, for 250 Km= 91 /100 x 250
= 22.51
Consumption by 6 cars = 6 x 22.51 = 1351
Difference between Gasoline Consumption = 1351-751 = 601
