Points A, B, and C are collinear and B is between A and C. You are given AC = 18 and BC = 4. What is the value of AB?

The value of AB is 14

Step-by-step explanation:

When we say a set of points are collinear, what we mean is that those points are on the same straight line i.e they lie on a straight line.

Now B is between A and C

Since B is between A and C

Then mathematically;

AC = AB + BC

18 = AB + 4

AB = 18-4

AB = 14

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
