If n3 is even then n is even?
Can't quite tell what you mean by n3. 1) If that's n3, then: If n3 is even, it can be expressed as n * n * n = 2 * t (t is a natural number). You can see that two is a factor of n3, and so it has to be a factor of n, because there is no ther number that could contribute to it. So n is even too. 2) If you mean 3 * n, then: 3 * n = 2 * t, where t is a natural number. Again, the only number to contribute factor 2 for the right side of equation is n. So n has to be even too.
How do you solve 6x - 3y 21?
Something needs to be an EQUATION in order for you to be able to SOLVE it. There's no "=" here so it's not an equation. What is the space between 3y and 21 supposed to mean? Clean it up!
Three children divided some marbles amongst themselves 1 child had half and 1 more The other took one more than half of those left The last kid took the remaining 8 How many marbles were ther in t?
If the third child took 8, and the second child took 1 more than half then he took 9, so then that's 17. If the first child took half of the original is 17 were taken by child 2 and 3, then double 17 is 34. So, Child 1 took 17 Child 2 took 9 Child 3 took 8
What is Emc square?
Correctly written it is E = mc^2 'E' is energy 'm' is mass 'c' is ther speed of light in a vacuum. It is the Einsteinian theory relating energy to mass. What it means is in a nuclear reactor , the mass of the nuclear fuel is converted into energy by the loss of mass. The mass placed in the reactor may be say 1 kg. It undergoes nuclear disintegration, forming two or more new elements of less mass ( say 0.999 kg) that the originsal mass . The loss being energy. !!!!! Notice it is a very tiny loss , but produces a huge amoint of energy.
What is the y-intercept for 5x - 4y equals 18?
5x - 4y = 18 Algebraically rearrange into the straight form ' y = mx + c'. Where 'm' is ther slope/gradient and 'c' is the y-intercept. 4y = 5x - 18 Divide both sides by '4' y = (5/4)x - 18/4 y = (5/4)x + 9/2 ( 4 1/2 = 4.5) So the slope is '5/4' and the y-intercept is 18/4 = 9/2 = 4 1/2 = 4/5 ( depending on how you have drawn the y-axis.
