Try a few questions right now.

Add 8 to both sides: 5x = 35. Divide by 5: x = 7.

Slope is the change in y over the change in x: (17 − 5) / (6 − 2) = 12 / 4 = 3.

Distribute first: 3x + 12 = 2x + 19. Subtract 2x from both sides: x + 12 = 19, so x = 7.

Square before you multiply: f(−4) = 2(−4)² − 3 = 2(16) − 3 = 32 − 3 = 29. Squaring a negative gives a positive.

The $30 is charged once no matter what, so it stands alone. The $0.10 depends on how much data you use, so it multiplies g: C = 30 + 0.10g.

Cover up the clause between the commas and you are left with “The exhibit ___ open.” The singular subject “exhibit” takes the singular verb “remains.” The plural-sounding “photographs” is a distraction.

A month of practice should predict confidence, but the sentence says the opposite happened. That is a contrast, and “Nevertheless” is the only contrast word offered.

Items in a list are separated by commas, and a comma never belongs between a verb and its first object, or right before the last item on its own.

The subject “plants” is plural and the sentence is describing a finished experiment, so the past tense plural “grew” fits. “Growing” is not a complete verb on its own.

Cheaper panels are the reason more people are installing them, so the sentence needs a cause-and-effect transition. The other three all signal contrast.

Write it as an equation: 0.4n = 26, so n = 26 / 0.4 = 65. Check it: 40% of 65 is 26.

Reopening the case signals a problem, so the account must disagree with the footage. “Conflicted” means disagreed; “aligned” and “coincided” both mean the opposite.

Set up the proportion 3/2 = 12/x. Cross-multiply: 3x = 24, so x = 8. Sanity check: flour tripled from 3 to 12 is 4 times, and 2 × 4 = 8.

The claim is about remembering, so the evidence has to measure recall. Only the delayed test does that. Word count, enjoyment, and preference say nothing about what students remembered.

Undo the addition first: x/4 = 7. Then multiply both sides by 4: x = 28. Picking 7 means stopping one step early.
