Experience the Quality With Free PERT Exam Questions That Helps Candidates Pass

The sentence directly links the action (extending weekend hours) to outcomes (backlogs shrank; wait times shortened). Option C captures that cause-and-effect relationship concisely. Options A and B contradict the stated results; option D invents a change not mentioned. On PERT Reading, main-idea items often compress multiple results into one clear statement. Signal words and parallel structure help: “after” introduces the change; two coordinated outcomes then specify the impact. In similar informational texts, look for verbs that indicate results (e.g., “reduced,” “improved,” “increased”) and be ready to abstract them into a single claim. Distinguishing between what changed (hours) and what improved (access and delays) is essential for accurate summaries—exactly the skill college courses expect when you digest policy statements, abstracts, or administrative updates.

Explanation (150–250 words):

First, add 5 to both sides to isolate the variable term: 8x=328x = 32. Next, divide both sides by 8: x=4x = 4. Option B is correct. Quick substitution verifies: 8(4)−5=32−5=278(4)-5=32-5=27, so the equation balances. On PERT math, single-variable equations like this test mastery of inverse operations and arithmetic accuracy. Many errors occur from subtracting instead of adding the constant or dividing incorrectly. Always proceed step by step: undo subtraction/addition first, then undo multiplication/division. A sanity check—if x=4x=4, left-hand side is near 32, minus 5, about 27—fits. This habit avoids last-minute slips and builds confidence with more complex algebra problems.

Subtract 5x5x from both sides: x−13=11x - 13 = 11. Add 13 to both sides: x=24x = 24. Option C is correct. Linear equations on PERT require systematically isolating the variable using inverse operations. A reliable approach is to first gather variable terms to one side and constants to the other, which reduces sign mistakes. Always keep equality by performing identical operations on both sides. A quick check validates: 6(24)−13=144−13=1316(24) - 13 = 144 - 13 = 131 and 5(24)+11=120+11=1315(24) + 11 = 120 + 11 = 131; both sides match. Mastery of this process allows you to tackle word problems that translate to equations and multi-step items involving parentheses and fractions. When in doubt, rewrite each step and re-verify arithmetic to avoid small slips that can flip a correct method into a wrong answer.

Average speed = total distance ÷ total time. 180 ÷ 3 = 60 mph. Option C is correct. The PERT math test frequently uses distance-rate-time problems to test proportional reasoning and problem solving. These real-world applications ensure students can translate math concepts into practical contexts like travel and physics.

Radius = diameter ÷ 2 = 7. Area = πr2=3.14×72=3.14×49=153.86\pi r^2 = 3.14 \times 7^2 = 3.14 \times 49 = 153.86. Rounded = 153.9. Option C is correct. On PERT, be careful to halve the diameter before squaring. Forgetting to do so doubles error magnitude.
