7(2e-1)-3=6+6e
14e-7-3=6+6e
14e-10=6+6e
+10 +10
14e=16+6e
-6e -6e
8e=16
8e/8=16/8
E=2
4(m-2)=24
4m-8=24 distributive property
add 8 to each side
4m=32
divide each side by 4
m=8
Cost per friend will be total cost of cab ride / number of friends
so z = 12.75 / y
If the hat is 15% off, then he will pay = 100 - 15 = 85%
So, He is wrong (not correct)
Hope this helps!
Answer:
379,442 AU
Step-by-step explanation:
The angle bisector is the altitude of the triangle. The resulting right triangle has a distance of 1 AU opposite the 0.000151° angle. The length we're interested in is the hypotenuse of the triangle. The relevant trig relation is ...
Sin = Opposite/Hypotenuse
Hypotenuse = Opposite/Sin
E-S distance = (1 AU)/sin(0.000151°) ≈ 379,442 AU
The star is about 379,442 AU from Earth.
