Free GED Exam Questions That Helps Candidates Pass

A toaster converts electrical energy into thermal energy (heat) to toast bread. Option A is correct. Option B reverses the direction. Option C applies to generators, not appliances. Option D describes food digestion, not a toaster. GED Science requires identifying forms of energy and transformations: electrical → light/heat in lamps; chemical → mechanical in cars; radiant → chemical in photosynthesis. Strategy: identify input (electric plug) and output (heat for toasting). Matching these clarifies the transformation type.

The Three-Fifths Compromise (1787) resolved disputes between Northern and Southern states during the Constitutional Convention. It counted enslaved individuals as three-fifths of a person for purposes of representation in Congress and taxation. Option B is correct. Option A (Missouri Compromise, 1820) regulated slavery in new territories. Option C (Compromise of 1850) addressed slavery in land won from Mexico. Option D (Great Compromise) concerned legislative structure, not slavery. On the GED, connect compromises to issues: Three-Fifths = representation/taxation; Missouri = balance of free/slave states; 1850 = fugitive slave law/California statehood.

Option B is clear and uses “because,” the simplest causal connector. Option A is wordy. Option C is verbose with “on account of.” Option D is awkward and passive. GED writing rewards concise, direct language. Strategy: replace long phrases (“due to the fact that”) with single words (“because”). Strong writing emphasizes clarity, not length.

Isolate the variable step by step. Subtract 4 from both sides: 7x=217x = 21. Divide by 7: x=3x = 3. Recheck—this equals Option B, not D. Correct answer: B (3). Always verify: 7(3)+4=21+4=257(3) + 4 = 21 + 4 = 25. True. Common GED mistakes include rushing arithmetic or misaligning subtraction. Strategy: rewrite each step clearly, then plug solution back to confirm. This prevents careless errors. GED algebra questions often test one-step or two-step linear equations, reinforcing inverse operations and solution checks.

This is a two-step linear equation with a fraction, a common GED Math skill. Start by isolating the fractional term. Subtract 5 from both sides: x3=11−5=6\dfrac{x}{3} = 11 - 5 = 6. To clear the denominator, multiply both sides by 3: x=6×3=18x = 6 \times 3 = 18. Therefore, the solution is x=18x = 18 (Option C). A quick check confirms the result: 18/3+5=6+5=1118/3 + 5 = 6 + 5 = 11, which matches the original equation. Frequent errors include adding instead of subtracting (leading to 16) or multiplying the wrong side only when clearing the fraction. Best practice on the GED: 1) perform inverse operations symmetrically on both sides, 2) clear fractions by multiplying every term by the denominator, and 3) verify by substitution. Recognizing structure—term with variable plus constant equals number—helps you plan steps in order: undo addition/subtraction, then undo multiplication/division. Keeping work neat prevents sign mistakes and speeds checking under timed conditions.
