Question

A. -3 B. 6 C. 5 D. -4

Answer 1

Answer:

B

Step-by-step explanation:

So we want to find the value of x.

Note that the entire segment (JK) is the sum of the segments JI and IK. In other words:

$JK=JI+IK$

We know that JK is (2x-1), JI is (2), and IK is (x+3). Substitute:

$2x-1=(2)+(x+3)$

On the right, add:

$2x-1=x+5$

Add 1 to both sides:

$2x=x+6$

Subtract x from both sides. The right cancels:

$x=6$

And the value of x is 6.

Our answer is B.
