Set 13: Linear Equations (Advanced)

Explanation

Answer: D

Solve for $F$ : $C = \frac{5}{9}(F - 32)$

F = (9/5)C - 32

F = (5/9)C + 32

F = 9C/5 - 32

F = (9/5)C + 32

✓ Correct

Detailed Explanation

Choice D is correct. Choice D is the correct answer. 1. Start: $C = \frac{5}{9}(F - 32)$ 2. Multiply by 9/5: $\frac{9}{5}C = F - 32$ 3. Add 32: $F = \frac{9}{5}C + 32$ Choice C is incorrect because fraction flipped. Choice A is incorrect because sign error. Choice D is incorrect because sign error.

Key Steps:

•

The correct answer is F = (9/5)C + 32

Why others are wrong:

A: Choice A is incorrect and may result from a calculation error.

B: Choice B is incorrect and may result from a calculation error.

C: Choice C is incorrect and may result from a calculation error.
