Free STAAR Exam Questions That Helps Candidates Pass

Expand the equation: 5(x−2)+3=185(x - 2) + 3 = 18. Distribute: 5x−10+3=185x - 10 + 3 = 18. Simplify: 5x−7=185x - 7 = 18. Add 7: 5x=255x = 25. Divide both sides by 5: x=5x = 5. Option C is correct. Option A (1) results from mis-subtracting 2 incorrectly. Option B (3) is a common distractor from forgetting to distribute properly. Option D (7) results from dividing incorrectly after adding. STAAR mathematics objectives emphasize solving linear equations with parentheses and constants, requiring mastery of distributive property and inverse operations. Students should verify by substituting: 5(5−2)+3=15+3=185(5 - 2) + 3 = 15 + 3 = 18, which matches the right-hand side. Accuracy and double-checking through substitution are skills emphasized by STAAR standards.

The Declaration (1776) formally separated colonies from Britain. STAAR History requires linking documents to purposes.

Perimeter = 2(l + w) = 2(15 + 7) = 44 cm. Option A is correct. STAAR Math requires applying perimeter formulas.

Igneous rocks form when molten material cools and crystallizes. Sedimentary rocks (A) form from deposition of sediments. Metamorphic rocks (C) form from heat and pressure altering existing rocks. Fossiliferous (D) is a subtype of sedimentary. STAAR Earth Science concepts test the rock cycle and characteristics of rock types. Identifying igneous rocks as crystallized magma is foundational knowledge.

The nervous system processes information and directs responses. STAAR Science emphasizes functions of major organ systems.
