<h2>Answer:     </h2>

<u>Number lines</u>                            <u> Inequality</u>

First                   ⇔              \dfrac{x}{4}\leq\dfrac{-3}{2}

Second             ⇔              \dfrac{-75x}{4}>\dfrac{225}{2}

Third                 ⇔              \dfrac{2x}{3}>\dfrac{-16}{3}

Fourth              ⇔              \dfrac{7x}{9}>\dfrac{-14}{3}

<h2>Step-by-step explanation:</h2>

Inequality 1. \dfrac{7x}{9}>\dfrac{-14}{3}

Multiply both sides by 9 , we get

7x>-42

Divide both sides by 7, we get

x>-6 which is shown by the fourth number line.

Inequality 2. \dfrac{-75x}{4}>\dfrac{225}{2}

Multiply both sides by 4 , we get

-75x>450

Divide both sides by -6, we get

x which is shown by the second number line.

Inequality 3. \dfrac{x}{4}\leq\dfrac{-3}{2}

Multiply both sides by 4 , we get

x\leq-6 which is shown by the first number line.

Inequality 2. \dfrac{2x}{3}>\dfrac{-16}{3}

Multiply both sides by 3 , we get

2x>-16

Divide both sides by 2, we get

x>8 which is shown by the third number line.

The first answer of part A is 32

So 4y means you have to multiply 4 by y, which is 20 since 4x5=20

And then you add 12, which is 32.

The second answer to part A is 40

With the second question of part a, the expression is basically saying 4 times whatever 5+3 is. So 5+3= 8, and 4(8) is 40

For part B, they are equivalent because let’s pretend y=2. 12+4y= 20. And then 4(y+3) would equal 20 because 4(2)=8 and 4(3)=12 and 8+12=20. This might not be the answer that your teacher is looking for, but it’s still a right answer so technically they can’t say it’s wrong unless you have a super unfair teacher

Mrac [35]
There are 60 minutes in one hour.
Divide 60 minutes by 10 minutes.

You get 6. That means you would need 6 recycled bottles to power a washing machine for one hour (that will be awesome if that were the case).

Have an awesome day! :)
