Answer:
K = 42
Step-by-step explanation:
K/2 = 21
2* k/2 =2*21
k=42
Answer:

Step-by-step explanation:
So we know that:

And that the two angles are vertical angles.
Since they are vertical angles, their measurements are equivalent. Thus, to find x, set the equations equal to each other:

Now, solve for x. Add 30 to both sides. The left side cancels:

Now, subtract 2x from both sides. The right cancels:

Thus, the value of x is 21.
Answer: [6x]
Step-by-step explanation:
(8 - 9x) = [1x]
(-10 + 7x) = [17x]
(14 - 16x) = [2x]
(12 - 24x) = [12x]
12x - 2x - 17x - 1x =
10x - 16x = [6x]
Answer:
t=-6
Step-by-step explanation:
12/2=6
t-6=3t/2-3
t-3t/2=-3+6
2t/2-3t/2=3
-t/2=3
-t=3*2
-t=6
t=-6
I believe if I’m not wrong the answer should be B 1/6
