Answer:

Carlos = 16

Dan = 64

Karen = 9

Step-by-step explanation:

Let Carlos be x

Dan = 4x

Karen = x - 7

Their total is 89

Create an equation of Carlos + Dan + Karen = 89

x + 4x + x - 7 = 89

Combine like terms

6x - 7 = 89

Add 7 on both sides to get rid of 7

6x = 96

Isolate x by dividing by 6 on both sides

x = 16

Substitute the amount of orders each person served

Carlos = 16

Dan = 64

Karen = 9

Hope this helps :)

Have a great day!

If segment AB is 4 units, segment AD is 23 units, and segment CD is 12 units, what is the length of segment BC?
Thepotemich [5.8K]

Answer:

<h2>C . 7 units</h2>

Step-by-step explanation:

The question is lacking appropriate diagram. Find the diagram to the question attached.

From the diagram, it can be seen that AD = AB+BC+CD

Given the following

AD = 23units

AB = 4units

CD = 12units

To get C=BC, we will substitute the given segments into the expression above as shown;

23 = 4+BC+12

23 = BC + 4 + 12

23 = BC+16

Subtract 16 from both sides

23-16 = BC+16-16

7 = BC

<em></em>

<em>Hence the length of segment BC is 7units.</em>
