The value of the variable x equation 0.2x+0.2+0.5x=-0.3x+1.2 is x=1.
Given a linear equation 0.2x+0.2+0.5x=-0.3x+1.2
Equation is a combination between two or more variables which is usually expressed in equal to form. Equation of two variable looks like ax +by=c. It is solved to find the quantity of x.
Given equation is as under:
0.2x+0.2+0.5x=-0.3x+1.2
It is a linear equation and will have only 1 solution. Linear equation is a equation which is having a straight line graph.
Adding the coefficients of variable
0.7x+0.2=-0.3x+1.2
Take -0.3 to other side
0.7x+0.3x=1.2-0.2
Adding the coefficients of variables
x=1
Hence the value of x in the equation 0.2x+0.2+0.5x=-0.3x+1.2 is x=1.

Prime numbers are number that can't be divided except it is it's self and 1. For example, 3,5,7,11,13,17, 19, 23, 29, 31, 37...... All of those numbers can only be divided with itself and 1.
3 = 3x1
7 = 7x1
23= 23 x 1
hope this helps
Answer:
6.84 ≤ x ≤ 37.39
Step-by-step explanation:
we have
-----> equation A
we know that
The company wants to keep its profits at or above $225,000,
so
-----> inequality B
Remember that P(x) is in thousands of dollars
Solve the system by graphing
using a graphing tool
The solution is the interval [6.78,39.22]
see the attached figure
therefore
A reasonable constraint for the model is
6.84 ≤ x ≤ 37.39
2/3x -8/3 >= y is the answer
