Which number can be added to a rational number a to explain that the some of rational number in the in rational number is inrational

You may add, for example, , or , to any fraction, and the result will be irrational.

In fact, we know that or can't be written as fraction. So, let's pretend that

which means, the sum of a fraction and an irrational is rational. This can't be true, because it would imply

And so we have written as a fraction, but this is impossible!

So, this proves that the sum of a rational and an irrational is irrational.

you divide the cost ($15) by the quantity (6) to get your questions answer. the yo-yo costs $2.50. hope this : )!

step-by-step explanation:

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
