We can't solve for x. There is no equal sign.

You can actually switch the calculator to a "fractions calculator"

To divide deciamals, you move the decimals over until you can divide easily.

Here's some examples:

The important thing to remember is that you have to move the decimal over in both the thing your dividing by, and the thing your dividing.

Then just carry the decimal up to your answer, and wala!

Waffles!

$$So this looks like:\\
$\frac{x+1}{1}$\\
I'm not sure what you want us to do with this. Simplify maybe?\\
You could simplify by taking the 1 on bottom away, because that isn't really necessary.\\
This would then simplify to:\\
$x+1$$$

$$$S = \frac{D}{T}$\\
Multiply both sides by T.\\
$S\times T=D$\\
Divide both sides by S\\
$T=\frac{D}{S}\\\\
Time = \frac{Distance}{Speed}$$$

First, we need to find the total number students at the library.

30 people did not like reading mystery stories, and that is 15% of the people.

15% of the total people = 30         --Let's have x equal the total number of students.

15% of x = 30

.15*x = 30         ---Divide both sides by .15

x = 200

200 people is the total amount of students. 85% of them like mystery stories.

85% of the total amount of people = people that like mystery stories      --Let's have y = people that like mystery stories

85% of the total amount of people = y

85% of 200 = y

.85*200 = y

170 = y

170 people like mystery stories.

Part A:

It doesn't say whether we want the maximum volume in cubic inches or cubic centimeters, but we have to convert the dimensions (height, width, length) into the same base to get an answer. Let's convert all the dimensions to centrimeters, because it seems the easiest. You can then turn it back into inches if you need to.

The dimensions are 10 inches by 6 inches by 10 centimeters.

2.54 cm in an inch, so 10*2.54 and 6*2.54 tells us these measurements in cm.

10*2.54 = 25.4

6*2.54 = 15.24

Our new dimensions are 25.4 cm by 15.24 cm by 10 cm

To get the volume, multiply length times height times width.

$$25.4\;cm\times15.24 \;cm\times 10 \;cm = 3870.96\; cubic \;cm$$

So our answer is 3870.96 cubic cm.

Part B:

We are also told 1 cup = 14.44 cubic inches.

Mike poured 15 cups into the container.

15*14.44

216.6 cubic inches

Part C:

Disclaimer: I'm not quite sure if this is how you do this part...but I'm pretty sure this is right.

We know that 216.6 cubic inches is how much water there is in the container. Let's turn this to cubic cm.

216.6*2.54 = 550.164 cubic cm.

Our dimensions in cm are 25.4 cm by 15.24 cm by 10 cm.

Now just divide this by length and width and we'll get how high the water went up to in this container.

550.164 ÷ 25.4 ÷ 15.24 = 1.421259842519685

Or, rounded to the nearest hundredth, 1.42 cm.

$$Well, just put in \mathbf{2.8} for c.\\
$6-|3c+7|\\
6-|3(2.8)+7|\\
6-|8.4+7|\\
6-|15.4|\\
6-(15.4)\\
-9.4$$$

This happens to me too Melody. I think rosala has said this has happened to her aswell.

I'm not quite sure what causes this. Maybe someone who is good with computers can help. :)
