1.) 28-3x-4= 2x+12+x
2.) 24-3x= 3x+12
3.)24-6x=12
4.)-6x=-12
5.)x=2
80*x + 210 = 490 ;
80*x = 280 ;
x = 280÷80 ;
x = 3.50 ;
For this case we have the following expression:

Multiplying we have:

We round the expression and we have that it is equivalent to: 20.
Thus,
is approximately equal to 20.
Answer:
The expression given is approximately equal to 20.
Option C
The slope of the given line is ∆y/∆x = (4-6)/(5-1) = -2/4 = -1/2. The slope of the desired (perpendicular) line is the negative reciprocal of this, -1/(-1/2) = 2.
The point-slope form of the equation for a line with slope m through point (h, k) is
... y - k = m(x - h)
For slope 2 and the given point, your equation can be
... y + 6 = 2(x + 2)
