Answer 2

Let's solve these equations step by step:

1. A:(400-300) = 8 First, calculate the expression in the parentheses: A: (400 - 300) = A: 100 Now, divide A by 100 to solve for A: A/100 = 8

   To isolate A, multiply both sides by 100: A = 8 * 100 A = 800

   So, A is equal to 800.

2. 45 ÷ 5 × b = 900 First, perform the division: 45 ÷ 5 = 9 Now, you have: 9 × b = 900

   To isolate b, divide both sides by 9: (9 × b) / 9 = 900 / 9 b = 100

   So, b is equal to 100.

To summarize: A = 800 b = 100
