4 0

Answer:

25 percent

Step-by-step explanation:

Percent decrease = (original - new)/original * 100 percent

                              = (40-30)/40 * 100 percent

                              = 10/40 * 100 percent

                              = .25 * 100 percent

                               =25 %

romanna [79]

 4x-7\leq 9  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.

⇒ 4x-7

But , according to question Dwight builds at most 9 models i.e.

⇒ 4x-7\leq 9

⇒ 4x\leq 16

⇒ \frac{4x}{4}\leq \frac{16}{4}

⇒ x\leq 4

Therefore ,  4x-7\leq 9  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 .

We are asked to simplify the expression \large\pmb{7x^2-x^2}.

\triangle~\fbox{\bf{KEY:}}

  • Combine like terms! :)

That's exactly what we need to do - combine like terms.

So, we subtract:

\star~\large\pmb{7x^2-x^2}

Which gives us:

\star~\large\pmb{6x^2}

Hope it helps you out! :D

How do you solve this equation?
Ivenika [448]
To solve this question, what you would need to do is add 30 to both sides of the equation and then divide by 9, to find the solution.

You can check if it is correct by substituting the same value back into the original equation and seeing if the left hand side is equal to the right hand side.
