Answer

C 77=7b ### D 9=b-2 Explanation 1. Solve for b in each equation A: 2b = 211 \Rightarrow b = \frac{211}{2} = 105.5 B: b + 18 = 7 \Rightarrow b = 7 - 18 = -11 C: 77 = 7b \Rightarrow b = \frac{77}{7} = 11 D: 9 = b - 2 \Rightarrow b = 9 + 2 = 11 E: 11 = \frac{33}{b} \Rightarrow b = \frac{33}{11} = 3

Explanation

1. Solve for $b$ in each equation<br /> A: $2b = 211 \Rightarrow b = \frac{211}{2} = 105.5$<br /> B: $b + 18 = 7 \Rightarrow b = 7 - 18 = -11$<br /> C: $77 = 7b \Rightarrow b = \frac{77}{7} = 11$<br /> D: $9 = b - 2 \Rightarrow b = 9 + 2 = 11$<br /> E: $11 = \frac{33}{b} \Rightarrow b = \frac{33}{11} = 3$
