What grade are you in? and can u take a closer picture for the instructions XD

Yes. How do you know?

thankss XD

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:)

hope this helped.

(3xy^2z^2)(-3x^3y^3z)^2

((81*x^8)*y^10)*z^6

hope this helped.

2x + 3y=0

x+2y=-1

x=3

y=-2

hope this helped.

Trigonometry is a branch of mathematics that studies relationships involving lengths and angles of triangles. The field emerged during the 3rd century BC from applications of geometry to astronomical studies.

hope this helped.

3/4y-2/3x=12

y=((8*x+144)/9)

hope this helped

9^2=9*9=81

hope this helped

  13=4x

4x=13

4x/4=13/4

x=3.25

hope this helped

interesting:l

is that even a math question? it means the wise are wise so they dont need to ask, while the "fool" is i guess foolish and dumb so he/she asks stupid questions. (this is from "a wizard of earthsea" right?)

hope this helped

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.
