Question

24(2а+1) -0,8(20а-10) :16

Answer 1

24(2a+1) - 0,8(20a-10)/16

= 24(2a+1) - 0,05(20a-10)

= 48a + 24 - а + 0,5

= 47a + 24,5

Answer 3

To solve the expression, let's break it down step by step:

1. Start by simplifying the terms inside parentheses:

   2a + 1 is already simplified. 20a - 10 can be simplified to 20a - 10 = 20a - 10(1) = 20a - 10.

   Now the expression becomes: 24(2a + 1) - 0.8(20a - 10) : 16

2. Next, distribute the multiplication across the parentheses:

   24(2a + 1) = 48a + 24 -0.8(20a - 10) = -16a + 8

   The expression becomes: (48a + 24) - (16a - 8) : 16

3. Now let's simplify the division:

   (16a - 8) : 16 = (16a - 8) / 16 = a - 0.5

   The expression becomes: (48a + 24) - (a - 0.5)

4. Finally, simplify the subtraction:

   (48a + 24) - (a - 0.5) = 48a + 24 - a + 0.5 = 47a + 24.5

Therefore, the simplified expression is 47a + 24.5.
