Answer:
3/8 hours
Step-by-step explanation:
distance=speed/time=120/4=30km
time=distance/speed=30/80=3/8
I am unable to solve this problem.
$2,819.70 is the answer
You multiply .0325×12×72.30
You can perform all kind of operation that are one the inverse of the other, so that the value won't change. For example, you can multiply and divide by 2:

Or add and subtract 5:

Answer:
y = -2x + 16.
Step-by-step explanation:
The slope of the perpendicular line = -1 / slope of the given line
= -1 / 1/2 = -2.
Using the point slope form of the equation of a straight line:
y - y1 = m (x - x1)
y - 8 = -2(x - 4)
y - 8 = -2x + 8
y = -2x + 16 is the required equation.
