If the linear equation with one variable is x / 4 + 2 = –2. Then the value of x will be negative 16.
<h3>What is simplification?</h3>
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The equation is given below.
x / 4 + 2 = –2
Solving for x, we have
x / 4 + 2 = –2
x / 4 = – 2 – 2
x / 4 = – 4
x = – 4 × 4
x = – 16

5 People can be chosen in 1287 ways if the order in which they are chosen is not important.
Step-by-step explanation:
Given:
Total number of students= 13
Number of Students to be selected= 5
To Find :
The number of ways in which the 5 people can be selected=?
Solution:
Let us use the permutation and combination to solve this problem
![nCr=\frac{(n)!}{(n-r)!(r)!}](https://tex.z-dn.net/?f=nCr%3D%5Cfrac%7B%28n%29%21%7D%7B%28n-r%29%21%28r%29%21%7D)
So here , n =13 and r=5 ,
So after putting the value of n and r , the equation will be
![13C_5=\frac{(13)!}{(13-5)!(5)!}](https://tex.z-dn.net/?f=13C_5%3D%5Cfrac%7B%2813%29%21%7D%7B%2813-5%29%21%285%29%21%7D)

1.584 and I believe that you can round that yourself
It`s either 100,000 because there is only four 0`s making it 70,000 or it`s 700,000 and you made a mistake of not typing that last zero in which case the question would be pointless to ask because the answer is in the question.
It has a constant daily growth rate of 1.5
