Answer:
Step-by-step explanation:
Given.
(4x)/7 - 6 = -20
The x variable should be isolated on one side of the equation.
<u>Adding 6 to both sides of the equation.</u>
(4x)/7 - 6 + 6 = - 20 + 6
(4x)/7 = - 14
<u>Multiplying both sides of the equation by 7.</u>
(4x)/7 × (7) = - 14 × (7)
4x = - 98
<u>Dividing both sides of the equation by 4.</u>
(4x)/4 = - 98/4
x = - 24.5

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>
