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. Which inequality could be used to find the number of models Walt builds?

   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 .

Step-by-step explanation:

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 .

W《4

Step-by-step explanation:

D = 4W - 7

D《9

4W - 7《9

4W《16

W《4
