6+3x = 2(2 + x)
First we will need to open the parenthesis by multiplying the number that’s in front of them:
6+3x=4+2x
Now we need to separate the numbers from the X. By subtracting 2x from both sides:
6+3x=4+2x
-2x -2x
————————
6+x=4
Now we subtract 6 from both sides.
6+x=4
-6 -6
—————
X = -2

<span>If the Venn diagram
shows a universe with 26 elements and two different outcomes which are B and Y,
then the probability will be 7/6. The correct answer to the following
given statement above is seven over six or 7/6.</span>
If the satellite moves at a speed of 27,000 km p/h, your answer depends on the question.
This could be written in an algebraic expression, such as:
27,000x = S [for S stands for the ultimate speed of the satellite]
Of course, if this is a 3rd grade level question, I highly doubt they have even gotten started to including the alphabet into math.
So, I would suggest plugging 4 into X.
To explain this to her, just say that the speed needs to be multiplied by the amount of hours it has traveled. (I got 4 because there is a '4' in the question instead of 'for').
Meaning,
27,000 x 4 = 108,000 km per 4 hours
If her teacher decides to ask why that number, have her explain the question did not make sense so she plugged in a 4 to find an answer to a certain amount of hours.
Hope that helps a bit with the confusion!
