To find the jumber of customers in an hour, you just divide 800 by 40.
This gives you 20, meaning 20 customers per hour.
Then, you divide it by two to get 10 customers per half hour.
Step-by-step explanation:
The question above is answered below.
Consecutive numbers are set of numbers that follow one another in ascending or descending order, e.g. 1, 2, 3, 4, 5....
The sum of three consecutive numbers = 72
Let the unknown consecutive numbers be represented by x+1, x+2 and x+3 such that:

Remove the brackets

Collect like terms and simplify


Make 3x subject of formula by subtracting 6 from both sides


To obtain the value of x, divide through by the coefficient of x, which is 3. Hence;


Since x = 22,



The smallest of these numbers is 23.
Check,
23 + 24 + 25 = 72
Answer:
The answer is 3x^2-4x-4+1/2x-1
