I think the answer is shelter B
Let the number be x.
Triple the number means 3x
add 6 means 3x + 6
subtract the number twice 3x + 6 - x - x
the result is the number plus 3 means that the result is x + 3
So, combining these into an equation, we get:
3x + 6 - x - x = x + 3
If we solve this equation for x, we will get:
x + 6 = x + 3
The x will cancel out and we will get : 6 = 3
Therefore, this is a false statement.
The area would be approximately 12.57 or 4pi. I hope this helps
Area of a circle = pi•radius^2
to find midpoint, find the mean.
add the numbers together and divide by the amount of numbers there is:
10 + 20 = 30
30/2 = 15
15 is your answer
hope this helps
