6j+18n=558
6j+1/3*n=134
___________(-)

53n/3=424 => 53n=1272 => n=24

You put n in the first equation:

The perimeter of this square is 20 inches.
Rashid [163]

Answer:

Amaya is wrong.

Step-by-step explanation:

The perimeter of the square is 20 inches, which means each side of the square needs to add up to 20 inches. If the side length of that side Amaya pointed out is 4 inches, then the total perimeter would only be 18 inches, in another case, if they were talking about the area of the square/rectangle (now), it would be 20 inches. So, Amaya is wrong.

Write 5% as a decimal.
jolli1 [7]
You cannot do it that way.  Make sure the question you wrote is correct, because you would divide 5 by 100, not 100 by 5.  A simple way is to move the decimal point two points to the left.  5% as a decimal is 0.05.  

The answer is false if the question is written this way.

Which is the correct answer?
Montano1993 [528]

Answer:

I'm not sure but I think it is letter A

Step-by-step explanation:

Because first off 0 is divisible by any integer number meaning it has to be divide by a whole number not fraction. Also, 0 + 2 = 2 then you divide that by 4 is 0.5.
