Answer:
-3-3x=12
-3x=15 add 3 to both sides
x=-5 divide by -3 on both sides
x is equal to -5

Step-by-step explanation:
Answer:
n=-18
Step-by-step explanation:
subtract 8 from both sides.
then you do -10 subtracted by 8 and thats -18.
Answer:
answer is D
Step-by-step explanation:
The complete question in the attached figure
we know that
tan ∠AOB=opposite side angle ∠AOB/adjacent side angle ∠AOB
opposite side angle ∠AOB=1
adjacent side angle ∠AOB=√3
angle ∠AOB=pi/a radians
so
tan (pi/a)=1/√3---------> tan (pi/a)=√3/3
we know that
tan 30°=√3/3
30° is equal to pi/6 radians
and
angle (pi/a) belong to the I quadrant
so
(pi/a)=pi/6
a=6
the answer isa=6
Its 10 times farther because each time you add another exponent, you're multiplying by 10, and so the difference is 1 in this case. Therefore it is C--10
