What is the value of the variable and bc if b is between a and c. Ab=4x,bc=5x;ab=16

you have

4x = ab
5x = bc
16 = ab

5ab = 4bc
5(16) = 4bc
20 = bc
so, x=4

To find the value of the variable x, we can set up an equation using the information given.

We know that Ab = 4x, bc = 5x, and ab = 16.

Since Ab = 4x and ab = 16, we can substitute 4x for Ab in the equation ab = 16:

4x = 16

Next, we can solve this equation to find the value of x.

Divide both sides of the equation by 4:

4x/4 = 16/4

Simplifying, we get:

x = 4

Now that we have found the value of x, we can determine the values of the variables a, b, and c.

Since Ab = 4x, we substitute x = 4 into Ab = 4x:

Ab = 4 * 4

Ab = 16

And since bc = 5x, we substitute x = 4 into bc = 5x:

bc = 5 * 4

bc = 20

Therefore, the value of the variable x is 4, and the values of the variables a, b, and c are:

a = Ab = 16

b = 4

c = bc = 20
