Hey
km/3x-2x= 4
km/3=4+2x
km=3(4+2x)
km=12+6x
km-12=6x
x=km-12/6
so D is the answer
Answer: 160 miles.
Step-by-step explanation:
Equation = $142.40 = .24x + 104
Define Variable = x = number of miles driven
Solve Equation = Subtract 104 from each side:
38.40 = .24x
Divide both sides by .24:
160 = x
The van was driven 160 miles.
Angle E = 180 -45 -63 = 72 degrees
Using the Law of Sines
FD / sine (E) = ED / sine (63)
3.8 / 0.95106 = ED / 0.89101
side DE = 3.8 * .89101 / .95106
side DE =

So, we will be using point-slope form to construct this equation.
Point-slope form's general formula is as follows:
M is the slope,
Y₁ is the Y-coordinate of the point
X₁ is the X- coordinate of the point.
So, our slope is 3 (since the equation is given in slope-intercept form)
Our Y₁ is 7 and out X₁ is 4
So, now we just plug our numbers into the equation.
There's your equation.
Hope this helps!
