Hey there!
The main concept of pre-algebra is solving equations for variables in them.
For example, let's say you have the algebraic equation below.
x+1=3
With algebra, you need to figure what x is equal to. To do so, you will use inverse operations on both sides of the equation to isolate x one side, showing what it is equal to.
We would subtract 1 to both sides to isolate x on one side.
x+1-1=3-1
As you can see, +1-1=0, therefore, this would give us x+0, or just x. Now it is isolated and will show us what it is equal to.
x=3-1
x=2
Therefore, in our equation x+1=3, x would be equal to 2.
I hope this explanation helps! Have a great time here at Brainly!
Thank goodness for you I do not have a credit for the math question mark so I do thank goodness for you I did not know what you did do not answer please please answer answer question answer answer me thank the answer please please answer please please thank thank goodness
The answer is option B i.e., Point F because 0-2 there are 10 divisions and point J is before 2 so it is clear that point J has coordinate 1.6.
SOLUTION:
When looking at this diagram, you can see that CM is equivalent to AM as displayed below:
CM = AM
If:
CM = 7
Then that means that:
AM = 7
Therefore, your answer is:
AM = 7
