What Is an Algebraic Equation?
Which of the following are NOT algebraic equations?
Indicate __all__ such answers.
Correct!
[[snippet]]
This is an algebraic expression, not an algebraic equation, because it does not contain an equals sign.
Incorrect.

This answer contains an equals sign, so it is an algebraic equation.
Incorrect.

This answer _is_ an algebraic equation because it states that
$$\displaystyle 2.\overline{45}a^3 + 4.1a^2$$
is equal to
$$\displaystyle -12.\overline{3} + b$$.
That's right!

This is an inequality, not an equation, because it contains the inequality sign (>), meaning "is greater than."
Incorrect.

This answer _is_ an algebraic equation because it states that one algebraic expression,
$$\displaystyle \frac{4}{7}m$$,
is equal to another,
$$\displaystyle \frac{5\pi}{2}n^2 - \frac{1}{4}n$$.
$$\frac{4}{7}m = \frac{5\pi}{2}n^2 - \frac{1}{4}n$$
$$\sqrt{3} > \sqrt{x^2 + 4x + 5}$$
$$2.\overline{45}a^3 + 4.1a^2 = -12.\overline{3} + b$$
$$3x + 5(y^2 + 3) + 195x^3 - 0 = 4xy$$
$$7.6(3q + 5qr + 9r) - 0.9(q + r^2) + 8.07$$
Proceed to step
