Absolute values of numbers are positive.

So the equation would be:

|9| +|3| * (-3)(4)

= 9 + 3 (-3)(4)

And since -3 * 4 = -12, the equation continued:

= 9  + 3(-12)

= 9 + (-36)

Adding a negative number is the same as subtracting the corresponding positive number.

= 9-36

= -27

Since this is only an expression, you could only simplify it, not solve for x.

10x + 1 -3x

Group the terms together:

10x - 3x + 1

= 7x+1

The temperature dropped 18 degrees during 6 hours, so divide 18 by 6 to find the number of degrees it dropped per hour.

18/6 = 3 degrees Fahrenheit per hour.

I believe this page says it all:

It depends on what you mean by "solve".

You could be solving for many things such as the length of a side, the perimeter, the area, or the diagonal of the rectangle.

If you honestly need help, I suggest you repost this question with a more specific description of what you need to solve:)

I must say, I love the take on this.

Not many people will take the time to dissect questions like this, much less reply with a question. This just goes to show how very different disciplines such as linguistics and math can still overlap:)

13 = 4x

Divide both sides by 4 to get x. Here is a calculator to use if you would like a decimal answer: 

Or, leave the answer in fraction form:

x = (13/4)

By solving it:)

If your question was -3 times -4, it is 12. A negative number times a negative number results in a positive number.

If your question was -3 minus 4, it would be like spending 4 more dollars when you already have a debt of 3 dollars. That would be a debt of 7 dollars, or -7 in math terms.

Use the site calculator:

Numbers in the hundredths place generally are not small enough to need scientific notation.

However, if you absolutely must have that number (0.0755) in scientific notation, simply move the decimal point right so that one nonzero digit is before the decimal point.

= 7.55,

Then multiply it by 10 to the power of however many times the decimal point moved right:

= 7.55 * 10^-2

You can use this method to write just about any number in scientific notation, and vice versa.
