M is 3 and -3
p is all real number
r has no solution
If you divided 4.736 ÷ 100 you have to find the times 100 is in 473, is 4 times, then you have to find how many times is 100 in 736, is 7 times, then you have 36 but this is not a entire number then you add a 0, 100 is 3 times in 360, now you have a 6, you add two zeros, 100 is six times in 600. 47,36 is the answer.
For this case, the first thing we must do is define variables.
We have then:
x: number of trips.
y: amount of money remaining.
We now write the equation for each person.
For Kaisorn we have:

Pata Thom we have:

Answer:
The system of equations that represents this situation is given by:


The value of y = 40.
5x = 40
x = 8
180 = 40 + 40 + (2y + 20)
40 = y
C is a geometric sequence. the terms share a ratio of 5
