The document describes 4 math problems from a Grade 8 standardized test. Problem 1 asks students to solve a linear equation using properties of rational numbers. Problem 2 defines irrational numbers and converting repeating decimals to fractions. Problem 3 requires interpreting the equation for a linear function and examples of non-linear functions. Problem 4 involves estimating very large or small quantities using numbers in scientific notation.

The Correct Answer is 7/2 or equivalent: Solve linear equations
with rational number coefficients, including equations whose
solutions require expanding expressions using the distributive
property and collecting like terms.

The Correct Answer is D: This question asks students to know that numbers
that are not rational are called irrational. Understand informally that every
number has a decimal expansion; for rational numbers show that the decimal
expansion repeats eventually, and convert a decimal expansion which repeats
eventually into a rational number.

The Correct Answer is A, B, D: This questions asks students to
Interpret the equation y = mx + b as defining a linear function,
whose graph is a straight line; give examples of functions that
are not linear.
