Answer:
x = 1/4
Step-by-step explanation:
-7x - (-5-x) = -9(2x-1) -1
-7x + 5 + x = -18x + 9 - 1
combine like terms:
-6x + 5 = -18x + 8
add 18x to each side of the equation:
12x + 5 = 8
subtract 5 from each side:
12x = 3
divide both sides by 12:
x = 3/12 = 1/4

Answer:
D: 12
Step-by-step explanation:
The entire segment KI is composed of the segments KJ and JI. So:

We know that KI is 15.
KJ is (2x-15) and JI is (2x-6). Substitute:

Solve for x. Combine like terms:

Add 21 to both sides:

Hence, the value of x is:

We know that JI is 2x-6.
We will substitute 9 for x to find JI. So:

Hence, our answer is D.
