Answer: 337.5 km
Step-by-step explanation:
Use proportion:
2:75=9:x
2x=675
x=675/2
X=337.5
If the two angles are supplementary, they must equal 180 degrees
Y=-1/3x-6, for this line, the slope (m) is -1/3.
This is because the equation is in the slope intercept form: y = mx + b.
The perpendicular line to one with m = -1/3, is the negative reciprocal of m, we'll call it m2.
m2 = --3/1 = +3/1 = 3

Answer:
65
Step-by-step explanation:
The problem statement tells you ...
1.20x = 78
Dividing by the coefficient of x gives its value:
x = 78/1.20
x = 65
