Anything with an exponent of 0 is 0, except 0.  0^0 is undefined.

364 = 3n + 5

Subtract both sides by n.

364 - 5 = 3n + 5 - 5

359 = 3n

Divide both sides by 3.

359/3=3n/3

119.66666...=n

No,  this cannot be true,  for we need whole numbers to equal 'n' in our sequence.

Use what is known as Keep,  Change,  Flip.

Keep the first fraction,  change division to multiplication,  and flip the last fraction its reciprocal.

(-3/8) * (-10/9)

First off,  a negative times a negative is a positive,  so there is no need to keep the negatives in the expression,  really.

(3/8) * (10/9)

3 * 10 = 30

8 * 9 = 72

Simplify 30/72.  They are both divisible by 6.

30/6=5

72/6=12

Your final answer is 5/12.

No number is divisible by 0.  There is no answer,  this is supposed to be a trick question.

Multiply 83 by 15 percent in decimal form.  15%=0.15

83 * 0.15 = 12.45

12.45 is your answer.  I hope this helps!

To make a fraction,  put one answer over another number.   You must remember a fraction is another way of writing division... often a nicer,  neater way. 

For example,  your teacher gives you the problem 7 divided by 9.  You put 7 as your numerator,  on top.  You put 9 as your denominator,   on the bottom.  Whatever number is to the left of the division is your numerator,  your top number.  Whatever is to the right is your denominator,  your bottom number.  7 divided by 9 is the same as 7/9.

Set up an expression:

If it is 25% off,  we know we are going to subtract something from the original.

To find the 25% off the original price,  you would multiply the original price by 0.25,  25% in decimal form.

So our expression should look like this:  24-(24*0.25)

Now use the order of operations.  Solve inside of parentheses first.

24 * 0.25 = 6

Now subtract.

24 - 6 = 18

The kite costs $18 when on sale.

To solve 750 divided by 9,  I personally like to use fractions.  750 divided by 9 is the same as 750 over 9 (750/9).

Now,  we just simplify our fraction.  750 and 9 are both divisible by 3.

750/3 is 250.

9/3 is 3.

We now have 250/3.  However,  we can take a step further and simplify from an improper fraction to a mixed number.

3 goes into 250 83 times.  We have one left over afterwards,  so our answer is 83 1/3.

I hope this helps!  @-Happy7

The pythagorean thereom formula is a^2+b^2=c^2.  You will be finding for the slanted line,  and this is used on right triangles,  last I remember.  As for the rest....I can't remember right now,  sorry.

The answer is no number can be divided by 0.  Why this is,  is,  like,  You have 30 toys,  and you divide them by 0 people,  then,  that wouldn't make sense.  You can divide 0 by a number,  that is 0,  but no number can be divided by 0.
