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.

There is no illustration, so it is impossible to answer this question. I apologise.
If you cant count the cookies, or find the volume of the cookies, then it can be whatever.
infinity or zero :)
Answer:
No real roots
Step-by-step explanation:
Given
7x² + 5x + 1 = 0 ← in standard form
with a = 7, b = 5, c = 1
To determine the nature of the roots use the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 then roots are real and distinct
• If b² - 4ac = 0 then roots are real and equal
• If b² - 4ac < 0 then the roots are not real
Here
b² - 4ac = 5² - (4 × 7 × 1) = 25 - 28 = - 3
Thus the 2 roots are not real
