Answer:

\boxed{y=-5}

\boxed{-5=y}

Step-by-step explanation:

Division property of equality- is a dividing both sides of an equation by the same non-zero number it does not change the equation.

a÷c=b÷c for c≠0

Checking a solution.

1. First you had to rewrite the original equation

2. Then you substitute the value for the variable

3. Finally simplify.

First you had to divide by eight from both sides of an equation form.

\frac{8y}{8}= \frac{-40}{8}

-40/8=-5

40/5=8

8*5=40

5*8=40

Final answer: \boxed{y=-5}

Hope this helps!

What is the irrational number in This set: 12.89, square root of 12 and 12/144 ?
kifflom [539]
Good night, 

<span>Irrational numbers are those that can't be expressed as a fraction:

12.89 can be expressed as: </span>\frac{1289}{100}

\frac{12}{144}= \frac{1}{12}

<span>The above numbers can be expressed as a fraction, then the logical answer is: </span>\sqrt{12}

But we will check the answer: 

\sqrt{12}= \sqrt{2^{2}*3 }  =2* \sqrt{3} =3.4641016...

As you can see we can't express that number as a fraction, so that is te correct answer.
