Yes - if I had an irrational number x, and I added that to the number (7-x), I would end up with 7.If the number is irrational, it can be subtracted from a rational/integer to make another irrational.
It can be written as a fraction, so it is rational.
No because 7 is a rational number
The square root of 49 is 7, so it is rational.
It is a rational number because it can be expressed as a fraction in the form of 7/11
-7 is a rational number because it can be expressed as a fraction in the form of -7/1
The negative square root of 49 is -7. -7 is whole, integer, and rational number. It's not a natural or irrational number.
7 is rational.
rational
-7 is a rational number

Not necessarily. There are negative irrational numbers, such as negative pi, negative square root of 2, etc.. Some negative numbers that are rational include -2, -13, -8, -4/7, -241/39 etc.
No, it is rational.
