1. **State the problem:** We need to find the values of the expressions when $x=6$ and match them to the given options. 2. **Expressions and evaluation:** - Expression 1: $7 - x$ - Expression 2: $x^2$ - Expression 3: $\frac{1}{3} x$ - Expression 4: $x + 10$ 3. **Calculate each expression:** - $7 - x = 7 - 6 = 1$ - $x^2 = 6^2 = 36$ - $\frac{1}{3} x = \frac{1}{3} \times 6 = 2$ - $x + 10 = 6 + 10 = 16$ 4. **Match values to options:** - $7 - x = 1$ matches option D. - $x^2 = 36$ matches option C. - $\frac{1}{3} x = 2$ matches option A. - $x + 10 = 16$ matches option B. **Final matches:** - $7 - x = 1$ (D) - $x^2 = 36$ (C) - $\frac{1}{3} x = 2$ (A) - $x + 10 = 16$ (B)
