Answer:
Linear systems are systems of equations in which the variables are never multiplied with each other but only with constants and then summed up
Answer:
The answer is 5 + 3x ≤ 50
Step-by-step explanation:
5 + 3x ≤ 50 - 5
3x ≤ 45
Divide by 3, x = 15
Answer: x>=200
Step-by-step explanation:
For this case we have that the inverse variation is defined as:

Where:
k: It is the constant of proportionality
According to the statement we have:

We find the constant of proportionality:

Then we find the value of x when
:
