-5 to a set number is -5
It belongs to the interval (25, 27.3), or [-20.9, 10*pi], and infinitely more such intervals.It also belongs to the set of rational numbers, real numbers, complex numbers and quaternions.
-29 is an element of the real number system. That is to say, it belongs to the set of real numbers.

It belongs to the set ofrational numbers,decimal fractions,improper fractions (in decimal form),real numbers,complex numbers,quaternions.
Of the "standard sets" -10 belongs to: ℤ⁻ (the negative integers) ℤ (the integers) ℚ⁻ (the negative rational numbers) ℚ (the rational numbers) ℝ⁻ (the negative real numbers) ℝ (the real numbers) ℂ (the complex numbers) (as ℤ ⊂ ℚ ⊂ ℝ ⊂ ℂ). Other sets are possible, eg the even numbers.
-5 to a set number is -5
It is a rational and real number.
It belongs to any set that has -17 amongst its members.Given that this is schoolwork, the answer teacher probably wants is: the set of integers.It also belongs to the set of rational numbers, the set of negative integers, the set of real numbers, the set of complex numbers, the set {43.2, 98, -17, pi} and an infinite number of others.It belongs to the set of complex numbers in spite of having no 'imaginary' part. Real numbers are just special cases of complex number in which the imaginary part happens to be zero. Rational numbers are special cases of real numbers. Integers are special cases of rational numbers.

-29 is an element of the real number system. That is to say, it belongs to the set of real numbers.
Negative rational numbers; Negative real numbers; Rational numbers; Real numbers. The number also belongs to the set of complex numbers, quaternions and supersets.
