The thickness of the board was decreased from 3 / 4 inches to 9 / 16 inches.
Therefore,
So the board's thickness in inches decreased by
Answer:
x = - 11
Step-by-step explanation:
Given
5x + 2 = 4x - 9 ( subtract 4x from both sides )
x + 2 = - 9 ( subtract 2 from both sides )
x = - 11
divide the 2m by 9 then the -5 by 9
giving 2m/9 - 5/9
The standard form of an equation is Ax + By = C. In this kind of equation, x and y are variables and A, B, and C are integers. When we shift the variable terms to the left side of the equation and everything else to the right side, we get . This equation is now in standard form.
the standard form of your equation is
5y+10x=−2
There are three areas.
A1=l•w
A1=2•1
A1=2 units^2
A2=l•w
A2=5•2
A2=10 units^2
A3=l•w
A3=2•1
A3=2 units^2
Area of shape is A
A=A1+A2+A3
A=2+10+2
A=14 units^2
