Do  you get paid or something for moderating this site?

the answer would be 18, right?

nice try

mortal

y=amount of oz in can originally. 
x=number of oz of water every second comes out of the container. 
y-5x=58
y=5x+58

y-15x=28
5x+58-15x=28
-10x=28-58
-10x=-30
x=3
y=73

Hope this helps!

Sorry I'm saying this a little late, but thank you. This really helped, and now I understand the concept

you are finding 20% percent of 89, so the expression would be 0.2 times 89

this would leave you with 17.80, which you subtract from 89. The result is

$71.20.

Let me know if you have any questions!

If you mean 

8x+16 = 4(2x+4) 

then the answer is all real numbers. 

Using the distributive property of multiplication, the 4 on the right hand side would be distributed evenly among the parenthesis. 4 times 2x is 8x. 4 times 4 is 16

you would be left with

8x+16=8x+16

why is this flagged?

thank you very much

The answer to -17/9 divided by 1/3 would be -17/3

An easy way to do this is by setting up the equation like you would for multiplication. You use the reciprocal of the second fraction and just multiply as usual.

Use this site for help:

-1 1/6, or -7/6 times 1/4 would be    -7/24

Hope this helps!

(4*10^-6)(7*10^-6)

The answer would be

2 decimal eight times ten superscript negative eleven 

or you can write it as:

2.8*10^-11

Note:

The asterisk (*) symbolizes multiplication.

Just realized I mis-read the question lol. Thank you for your time though.

Thank you so much.

Happy early birthday!

Ok. 

x= -2, so you substitute the x for a negative 2. You then multiply -2 by -3, since a variable next to a coefficient signals multiplication. -2 times -3 is equal to positive 6. You then take that positive 6 and multiply it by -7. Negative times positive equals negative, so the answer is -42.
