Question

The sum of  2/3
 and the number represented by x is zero.
Drag and drop 2/3
 and x to their correct positions on the number line

Answer 1

help meee

Answer 2

I will give it a go but not sure about it. Maybe someone else can confirm.

So for 2/3, you can simply drag and drop it on the number line by locating 2/3.

For x, they have given you an equation...have you figured out what it is?

Answer 3

am I right

Answer 4

2/3 is in the wrong position. It should be on the positive side of the number line since its a positive number

Answer 5

oh ok like this sorry

Answer 6

Yes, looks correct now

Answer 7

For the x-value, they have given you a statement in the very first line of the question. Can you write it as an equation please?

Answer 8

ok thxs :) for ur help think u can help me with more

Answer 9

You're welcome.
I can surely have a look :)

Answer 10

so did I put x at right placd

Answer 11

'place'

Answer 12

No, its incorrect at the moment.
To know x, you need to look at the question.

They have said that when you add x and 2/3, the result is 0.

This can be written as:
\[x+\frac{ 2 }{ 3 }=0\]

Do you know how to work out the x value from here?

Answer 13

no not even a little bit

Answer 14

show me where would u put x on the line I showed u

Answer 15

Are you familiar with this: http://www.purplemath.com/modules/solvelin.htm

It explains how to solve linear equations for a given variable. You need to apply the same concept in this question to solve for x.

Answer 16

kinda I just want to pass it really bad

Answer 17

Unfortunately, I am not allowed to give you answers on this site but guide you to it :(

So here's the equation

x + 2/3 = 0

To get x, on its own, what do you think the first step would be? You can refer to the link I posted above for more explanation

Answer 18

I will give you an example

x + 3 = 0 and we are asked to solve for x

We can solve for x by getting rid of the '+3' from left side of the equation or making it equal to zero.

For it to equal zero, we can include '-3' on the left side of the equation. So now, it looks like:

x +3 -3 = 0

As a rule when solveing these types of equations, what you do to one side, must be done to the other side of the equation as well.

In this case, we need to add '-3' to the right side of the equation as well. So we have..

x +3 -3 = -3

Notice that +3 and -3 equal to zero, so we are left with..

x = -3

and thats all, we have solved for x. You can apply this same procedure to solve for x in your question.
