They are algebraic symbols or known as unknown number. There is no true value for them. The value of algebraic symbols are based on equations
ie. 1+x = 2
First, we isolate the x by canceling the +1 FROM BOTH SIDES(Balance method) by -1 ON BOTH SIDES.
1+x-1 = 2-1
So we are left with the x on the left side, and a single number on the right side. Therefore, our calculation is complete.
x = 1
More complex cases would be
2y-3 = 45
First, we need to isolate the algebraic symbol, which is 2y (yx2) by +3 ON BOTH SIDES
2y-3+3 = 45+3
2y = 48
WE ARE NOT DONE! 2y=48 is still an equation. Therefore, to isolate the y, we need to divide BOTH SIDES by 2
2y/2 = 48/2
y = 24
There is no true or absolute or definite value for algebraic symbols like x,y,z,a,c,t,h,d etc. They are used to represent unknown numbers.
Hope this helped!
Since, AB and BC are the same length, the measure of the chord for BC would be 12.5 units
Answer:
The average speed of Sebastian is 3 miles per hour.
<u>Solution:</u>
Given, In 
hours, Sebastian can walk 4 1/2 miles.
we have to find What is his average speed in hours per mile
We know that, average speed 
In our problem, total distance travelled = 
Now, average speed of Sebastian 
Hence, the average speed of Sebastian is 3 miles per hour.
