Set up an equation.  Your equation should look like this: n+(n+3)+(n+6)=36

n is the smallest number,  therefore n+6 is the largest.

To simplify your equation,  it looks like:  3n+9=36

Subtract 9 from both sides.

3n+9-9=36-9

3n=27

Now divide both sides by 3.

3n/3=27/3

n=9

The smallest number is 9.

To find the largest number,  add 6 to n.

9 + 6 = 15

The greatest number is 15.

The middle number is 9 + 3 = 12.  The middle number is 12.

We can go back and check our work.

9 + 12 + 15 = 36

9,  12,  and 15 are consecutive multiples of 3.

Therefore,  your answer is 15.

To put 7 1/2 on here,  what I do is this (7+(1/2)).  It works for me.

Thank you,  CPhill!!!

Integers are any whole numbers,  whether positive and negative,  and 0.

The set of integers looks like this: {...-3,-2,-1,0,1,2,3...}  The ... is called an elipse and shows that this set goes on forever.

752/8=94

Your answer is 94.  @-Happy7

Start by distributing -6 to x and -7 on the left side,  and distributing -2 to 4 and 3x on the right side.  This will cancel out our parentheses.

-6x-42=-8-6x

Now get x to one side of the equation.  Add 6x to both sides.

x ends up cancelling out on both sides.  There is no solution for x in this equation,  because you end up with -42=-8,  which is not a true statement.

Find out how many times 9 goes fully into 31. 

9 goes fully into 31 3 times.

How much is left over.

9*3=27  31-27=4

4 is what is left over,  this is your numerator.  9 is the denominator,  it stays the same.  3 is the whole number.

The answer is 31/9 is the same as 3 4/9.

Plug in values for variables.

-(-2)^2-(5(-2)-2(-4))+7(-4)

A double negative is a positive.

2^2-(5(-2)-2(-4))+7(-4)

Work inside parentheses.  Multiply.

2^2-(-10-(-8))+7(-4)

Subtract inside parentheses.

2^2-(-2)+7(-4)

Solve exponent.

4-(-2)+7(-4)

Multiply.

4-(-2)+(-28)

Add and subtract from left to right.

6+(-28)

-22

Your answer is -22.  I hope this helps!!!

z^3=343

7*7=49*7=343

z=7

Guest,  I see what you are saying.  This is a mistake on my hand.  I am still learning this stuff,  and I am glad I have people who can point out my mistakes.  Thank you!

Divide both sides by 4.

The answer is A/4=W

I hope this helps! @-Happy7/Ethan

Divide both sides by 4.

x + y = 2

Subtract x from both sides.

y = 2 - x

That is your answer!!

A multiple is any number that can be divided by another number to result a number.  So,  for multiples of 18,  you are looking for number that can be divided cleanly and result in 18.  To find multiples easily,  multiply 18 by numbers. 

18 * 1 = 18

18 * 2 = 36

18 * 3 = 54

18 * 4 = 72

18,  36,  54,  and 72 are a few of 18's multiples.

Note multiples can also be negative.

18 * -1 = -18

18 * -2 = -36

18 * -3 = -54

18 * -4 = -72

-18,  -36,  -54,  and -72 are also multiples of 18.  I hope this helps! @-Happy7

Let's set up an equation.

92.94=20.26+36.34h

Subtract both sides by 20.26.

92.94-20.26=20.26-20.26+36.34h

72.68=36.34h

Divide both sides by 36.34

72.68/36.34=36.34h/36.34

2=h

Now,  we must remember that the 36.34h was for each additional hour,  20.26 was for the original hour.

So we add on 1 to 2 and we find out the plumber was at that household for 3 hours.  I hope this helps,  and have  a great day! @-Happy7

A unit rate is a relationship between an independant and dependant variable.  For example,  miles per gallon is a unit rate.

If your car goes 32 miles on 2 gallons,  how far does it go on one gallon?  To solve the unit rate,  you say,  "OK,  I get 32 miles per 2 gallons,  so simplify the fraction by dividing both sides by 2.  I get 16 mpg."

This can also be written as 16 m / 1 g

I hope this helps! @-Happy7

Work inside parentheses first.

8 + 7 = 15

Now multiply.

9(15)=135

Your answer is 135.  I hope this helps! @-Happy7

Oops,  that is what I meant.  Sorry for that,  let me fix that mistake :)  Thanks!

2 * 3 ^ 1 = 2 * 3 = 6

2 * 3 ^ 2 = 2 * 9 = 18

2 * 3 ^ 3 = 2 * 27 = 54

2 * 3 ^ 4 = 2 * 81 = 162

The first four terms of this pattern are 6,  18,  54,   and 162.
