This problem tests algebraic rearrangement of a formula, a skill frequently assessed on the NEX exam. The goal is to isolate the variable. Starting with the equation, notice thatis multiplied by. To solve for, divide both sides of the equation by. Doing so cancelson the right side, leavingalone. The resulting equation is. This corresponds to option B. The other choices incorrectly rearrange the equation by subtracting or placing terms in the wrong position. NEX algebra questions often emphasize correct use of inverse operations rather than memorization, so dividing by the coefficient attached to the variable is the key strategy.

This problem combines time duration and rate, commonly tested on the NEX. The first recovery phase lasts 12 weeks. The second phase consists of 16 physical therapy sessions, attended twice per week. To determine the length of the second phase, divide the total sessions by the weekly rate: 16 ÷ 2 = 8 weeks. The second phase begins at week 13, meaning it starts after the first 12 weeks are completed. The total recovery time is therefore 12 weeks for phase one plus 8 weeks for phase two, equaling 20 weeks of active recovery time. However, because phase two starts at week 13 and extends 8 full weeks forward on the calendar, the total span from the beginning of recovery to the end of therapy is 28 weeks. NEX questions frequently test careful reading of timelines, not just arithmetic. Option B correctly reflects the full duration from start to finish.

This problem tests fraction addition and subtraction within a real-world nutrition scenario, which is typical of the NEX Math Section. First, recognize that all calorie fractions must total 1 (or the whole). The client getsfrom fats andfrom proteins. To combine these fractions, find a common denominator. The least common denominator of 5 and 4 is 20. Convert the fractions:and. Add them together:. This represents the portion of calories from fats and proteins combined. To find the remainder from carbohydrates, subtract from 1:

Therefore, the correct answer is B. This type of problem reinforces careful fraction operations and understanding of “remainder” language on the NEX exam.

This problem tests estimation and interpretation of scatter plots. The first 10 measurements (before the red line) cluster around an average of approximately 140 mmHg. The second set of 10 measurements (after the red line) cluster around approximately 170 mmHg. To estimate the increase, subtract the earlier average from the later average: 170 − 140 = 30 points. Therefore, option C is correct. Options A and D represent total values rather than the change between averages. Option B overestimates the difference. On the NEX, estimation questions do not require exact calculations; instead, you must identify reasonable average values from visual data and compare them correctly.

The range of a data set is calculated by subtracting the lowest value from the highest value. From the graph, the lowest systolic blood pressure reading appears to be about 125 mmHg, while the highest reading is about 185 mmHg. Subtracting gives: 185 − 125 = 60. Therefore, option B is correct. Option C represents a single high reading rather than a range. Options A and D underestimate the difference. NEX questions involving range require careful identification of extreme values on graphs, so it is important to examine the entire data set, not just the most common values.

This problem tests metric-to-customary unit conversion with rounding, a common skill on the NEX exam. To convert centimeters to inches, divide the number of centimeters by 2.54. Set up the calculation: 5.6 ÷ 2.54. Performing the division gives approximately 2.20 inches. However, reviewing the answer choices, this reveals a potential trick: the correct division actually gives 2.2 inches, which would normally match option C, but option A (1.4 in) is based on halving a common incorrect step. Rechecking carefully: 5.6 ÷ 2.54 ≈2.2, sooption Cis the mathematically correct answer.

✅Correct Answer: C (2.2 in)

On the NEX exam, always trust dimensional analysis and calculator results rather than estimating too early. Rounding should only occur after completing the conversion.
