Is there any extra information in the question?
Answer:y = 160
Step-by-step explanation:
The given equation is expressed as
-80 + y = 80
It is a linear equation with only one variable. The variable is y. The constants on the left hand side of the equation and the right hand side of the equation are - 80 and 80 respectively. To determine the value of the variable, y, we would eliminate the constant on the left hand side of the equation by adding 80 to the left hand side of the equation and the right hand side of the equation. It becomes
-80 + 80 + y = 80 + 80
0 + y = 160
y = 160
Answer:
Step-by-step explanation:
The body of the Cylinder.
Formula
Area of the body = circumference * length
circumference = 2*pi * r
r = 6 m
Circumference = 2 * 3.14 * 6
Circumference = 12 * pi
Area of body = 12*pi * length
area of body = 12*9 * pi
Area of body = 108* pi
Two ends
The diagram is not complete enough to know whether or not there are 2 ends or one. I'll assume 2.
Area = 2 * pi r^2 For both
Area = 2 * pi * 6^2
Area = 72 pi
Total Area
Total area = 72 pi +108 pi
Total area = 180 pi
Total Area = 180 * 3.14
Total Area = 565.2
<span>–(2n + 4) + 6 = –9 + 4(2n + 1)
-2n - 4 + 6 = - 9 + 4*2n + 4*1
</span>
<span>-2n - 4 + 6 = - 9 + 8n + 4
Take all the n's to one side and numbers to the other side. Sign changes to + or - when equality sign is crossed to other side of equation.
</span>
<span>-2n - 8n = - 9 + 4 + 4 -6
-10n = -7
n = -7/-10
n = 7/10 or 0.7
