find a counterexample for the following statement. If a number is divisible by 5, then it is divisible by 10. What is the counterexample of that statement?
To find a counterexample for the statement "If a number is divisible by 5, then it is divisible by 10," we need to find a number that is divisible by 5 but not by 10.
To do this, we can consider the number 5. We know that 5 is divisible by 5 since it is a multiple of 5, but 5 is not divisible by 10 since it does not evenly divide into 10. Therefore, 5 is a counterexample to the statement.
In general, any number that is divisible by 5 but not divisible by 10 would serve as a counterexample. Another example is 15, which is divisible by 5 (3 times), but not by 10.
So, the counterexample to the statement is the number 5 (and any other number divisible by 5 but not by 10).
What about the number 25?
thank you very much..ok i have another question..
in the square qrst and line qt is congruent to line ts and line rs is congruent to line ts, what is x? line qt=1/2(14x+8) and line rs= 6x+8 what is x?
all sides of a square are equal. So set the two measurements equal to each other in an equation.
1/2(14x + 8) = 6x + 8
You will get x=4 as your answer.
