inequality could be used to find the number of models Walt builds. Correct option B).
<u>Step-by-step explanation:</u>
Here we have , Dwight and Walt are building model cars. Dwight builds 7 fewer models than 4 times the number Walt builds.Dwight builds at most 9 models. We need to find Which inequality could be used to find the number of models Walt builds . Let's find out:
Let the the number Walt builds is x , So Dwight builds 7 fewer models than 4 times the number Walt builds i.e.
⇒ 
But , according to question Dwight builds at most 9 models i.e.
⇒ 
⇒ 
⇒ 
⇒ 
Therefore ,
inequality could be used to find the number of models Walt builds which is Dwight builds at most 9 and Walt builds at most 4 .
Since AB and BC are two parts of AC, AC = AB + BC
let's plug the expressions from the question into our equation above.
19 = 3x + 1 + 2x - 7
Combine like terms
19 = 5x - 6
Add 6 to both sides.
25 = 5x
Divide both sides by 5
5 = x
