It's prefectly OK to look up the formula. It's a pretty big hint though.

Also, another hint: I carry items to be sold at stores.

Ok, so kitty is writing out an algebraic equation to solve this word problem.

The problem said that there were the same amount of bricks in the bottom three rows. The number of bricks is represented by x.

So, 3x tells us how many bricks there are in the bottom 3 rows.

The next 6 rows will have 2 blocks few than the one before it.

So, the next row will have x-2 bricks, the next row will have x-4 bricks, the next will have x-6, then x-8, x-10, x-12

This is 6 rows so we stop there.

Now we know the total number of bricks used is 156, so we set all this equal to 156, and we get:

3x + (x - 2) + (x - 4) + (x - 6) + (x - 8) + (x - 10) + (x - 12) = 156

(then kitty solved for x, which is the number of bricks on the bottom 3 rows, and then you can figure out the number of bricks on the other rows from that answer)

Here's a picture so you can visualize it:

To find the first numbers percentage of the second number, divide the first number by the second number.

$${\frac{{\mathtt{111\,682\,718\,531\,813}}}{{\mathtt{111\,738\,001\,027\,711}}}} = {\mathtt{0.999\: \!505\: \!248\: \!927\: \!047\: \!7}}$$

Change this deciml to a percent by moving the decimal over 2 places to the right and addig a percent.

99.95052489270477%

or, rounded to the nearest hundredth of a percent,

99.95%

kitty i dint understand how did u form that equation!can u please explain ur answer to me much more nicely!

You would first write this problem as an equation. Let's use x as the variable:

3x + (x - 2) + (x - 4) + (x - 6) + (x - 8) + (x - 10) + (x - 12) = 156

Simplify the equation by combining like terms (the x's and constants):

3x + 6x - 42 = 156

9x - 42 = 156

Add 42 to both sides:

9x = 198

Divide by 9:

x = 22

Now x represents the number of blocks in the bottom 3 rows. For the next 6 rows, just subtract two blocks from the row below it.

For example, the fourth row (from the bottom up) would be (x - 2) = 20 blocks.

The 5th row would be (x - 4) = 18 rows, and so on and so forth:)

umm!i dont understand this properly!can u give another hint!

An improper fraction is one in which the numerator is greater than the denomintaor!some examples of improper fractions are 5/2 , 6/5 , 3/2 !

if u want to understand more nicely then heres a website that could help u !

Thanks, kitty<3. Wish you the same thing!

You're welcome, rosala.

thats very sweet of you kitty to wish him that!

You are very welcome, DragonSlayer554. Good luck in math and in life:)

thanks!

Really kind.

your welcome!

Thanks, kitty<3 for the correct answer!

Thanks rosala. Thanks for checking the error!

yes the answer is absoloutely correct , i ws just correcting your mistake !

Since you want to convert that number to square feet, Anonymous, I'm assuming you meant 37200 square inches.

You would divide 37200 by 144, since 1 foot equals 12 inches. 1 square foot would equal (12*12) square inches, or 144 square inches.

So $${\frac{{\mathtt{37\,200}}}{{\mathtt{144}}}} = {\frac{{\mathtt{775}}}{{\mathtt{3}}}} = {\mathtt{258.333\: \!333\: \!333\: \!333\: \!333\: \!3}}$$

It would be 258 and one-third square feet.

The answer is really long.

First. write this scenario into an inequality:

x/-6 > 3

Now multiply both sides by -6.

x < 3 * -6

(The inequality symbol is flipped because you are dividing by a negative number).

x < -18, so it would be the third choice.

To check, you can plug in a number less than -18 for x, such as -19.

$${\mathtt{\,-\,}}{\frac{{\mathtt{19}}}{-{\mathtt{6}}}} = {\frac{{\mathtt{19}}}{{\mathtt{6}}}} = {\mathtt{3.166\: \!666\: \!666\: \!666\: \!666\: \!7}}$$

3.16666... is greater than 3, so the answer is correct.

In my calculations, the answer is 1,383,840,000. Hope it helps!

Thanks, 7UP. So, it is 4 times the distance for the car to come into a complete stop?

Energy is half the mass times the square of the velocity.

$$2^2=4$$ (This 2 represents the (doubling) increase in velocity)

Disregarding other considerations, it will take 4 times the distance.

Sorry! I did a mistake! It was 63 million. But the answer is correct. LOL

Hello Anonymous,

To 'match each equation with its solution", you would need to solve each equation. First, write each term as an equation.  So here we go:

1st equation:  g/3 + 4 = 2

Subtract 4.

g/3 = -2

Divide by 3.

g = -6, so the first term would match to B.

2nd equation:  11 - u = -7

Subtract 11.

-u = -18

Divide by -1.

u = 18, so the second term matches to C.

3rd equation: y/2 - 7 = -13

Add 7.

y/2 = -6

Multiply by 2.

y = -12, so the third term matches D.

Now you can use the process of elimination to find that the fourth term matches A, but you can also work it out:

4th equation: 2n - 5 = 1

Add 5.

2n = 6

Divide by 2.

n = 3
