Answer:Yes
Step-by-step explanation:
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.

Answer:
see explanation
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the side length )
Given A = 55 , then
s² = 55 ( take the square root of both sides )
s = 
≈ 7 in ( to the nearest whole inch )
s ≈ 7.4 in ( to the nearest tenth of an inch )
