For which equation(s) is −2 a solution?

Answers

Answer:

A.) 2x+6=2

B.) 2(x-4)=6x

Step-by-step explanation:

A.) 2x+6=2:

Move all terms that don't contain  x  to the right side and solve.  

x=−2

B.) 2(x-4)=6x:

Solve for  x  by simplifying both sides of the equation, then isolating the variable.

x=−2

C.) 3x+1/2=1/4x+6:

Solve for  x  by cross multiplying.

x=2

D.) 3x+15=2x+9:

Solve for x  by simplifying both sides of the equation, then isolating the variable.

x=−6

Which of the following shows why the commutative property doesn't work under subtraction

Answers

Answer with explanation:

Commutative property under subtraction:

If a and b are any two real numbers such that,⇒ a-b =b-a, then we say that ,a and b Satisfy Commutative property under Subtraction.

Take any two real numbers

a=5.6

And,b=7

a-b

=5.6-7

= -1.4

b-a

=7-5.6

=1.4

So,a-b≠b-a

Therefore  , we can say that, real numbers doesn't satisfy commutative property under subtraction.

Option D:5-1≠1-5

This statement shows that, commutative property doesn't work under subtraction.

Hello!  To answer your question, you first need to know what the commutative property is and does.  Down to the basics, it lets you switch around numbers and it would allow me to say that 2+5=7 and 5+2=7.  This property also works in multiplication, because if I take 4*2=8, and 2*4 still equals 8.  Now that I've either refreshed or hopefully helped you to understand the property better, why wouldn't it work under subtraction?  If you switch numbers around in subtraction, will your answer still be the same?  Once you answer that, take a peak at the worksheet!  I hope this has helped in some way, and if you have any further questions send me a question or another message.  Good luck :)

Miley music has a sale on music CDs all music CDs are discounted 15% Marianas receipt indicates that she saved $3 on her CD purchase what is the full price of her music CD before the discount

Answers

Answer: The original price of her music CD before discount is $20.

Step-by-step explanation:

Let x be the original price of her music CD.

Discount rate = 15%

At discount she saved = $3

So, According to question, our equation becomes

15%x= 3

0.15x= 3

x=$20

Hence, the original price of her music CD before discount is $20.

If x is the price before a sale
x-0.15x=x-3
0.85x=x-3
3=0.15x
x=20

The original price is $20
