I need help because I think I know the answer but im not sure its right.

 

The choices are

 

1) 60x - 180

 

2) 10x - 40

 

3) 12x - 60

 

4) 12x - 36

There are two actions required.  First multiply everything inside the parentheses by 3.  Then, divide the result by 5.

 

First, multiplying by 3 gives us (60x – 180)

 

Then, dividing that by 5 gives us (12x – 36) 

 

You did the first part correctly, but neglected to do the second part.

 

The correct answer is number 4, which is 12X – 36  

 

You could have done the division first, then the multiplication, and obtained the same answer.

I will delete my rude remark but honestly, you go to the trouble of posting a question and you cannot even be bothered to READ the answer.

EVEN when the exact final answer is in BOLD print.

 

Perhaps you should be enrolled in a school for BLIND children

3/5(20x-60). First, you distribute. If you don't know what that means, it states that a(b+c)=ab+ac. So 3/5(20x-60)=(3/5*20x)-(3/5*60)= 20*3/5 = 4*3=12 so 20x*3/5=12x. 60*3/5=12*3=36.So 3/5(20x-60)=12x-36

Distributive property - we multiply everything in the parentheses by 3/5.

I like to multiply first, and then divide.

So, \(3(20x-60)=60x-180\) . We just multiplied 3 to 20x and -60.

Now, we can't forget the dividing by 5. Do this to 60x and -180.

Now we get 12x and -36.

Can you combine these and get the answer?

 

You are very welcome!

:P
